Administration Building of Singapore Management University ...

The Asian Welding Federation (AWF) held its 12th Task Force Meeting and its 19th General Assembly over two days, July 11 and 12, at the

Administration Building of Singapore Management University (SMU) in Singapore.During this meeting, each of the participating AWF member countries reported on their specific implementation plans for the Common Welder Certification Scheme (CWCS), which is a common welder certification scheme for Asia, and exchanged views regarding the Operating Procedures (OP) revisions. The implementation method itself was finalized at the last CWCS Task Force Meeting in Bangkok, Thailand.The Task Force Meeting held on July 11 began with an opening address by AWF Secretary General Ang Chee Pheng (formerly President of the Singapore Welding Society), after which new AWF members from each country briefly introduced themselves. Out of the 13 AWF member countries, only South Korea and Iran were absent from the meeting, which was attended by approximately 50 participants from 11 nations. In addition, a representative of an Australian welding industry body attended the meetings as an observer.

Proceedings commenced with review of the minutes of the previous meeting by the secretariat (Singapore). The minutes confirmed the approval of Regulations A001 (rules for the implementation of AWF guidelines on the testing and certification of welders for fusion welding), stipulating requirements for Authorized Testing Centers (ATC); the approval of Regulations A002 (requirements of certified testing centers), stipulating requirements for ATC; and the approval of OP01 to OP21.Next, there was a report from the Japan Welding Engineering Society (JWES) on its trial of a Welder Qualification Test (WQT) based on ISO 9606-1. Reactions and issues relating to the trial and differences in fabrication technologies were confirmed and a proposal was made to incorporate the results into OP12 (details of qualification testing of welders), with the aim of realizing the proposal as soon as possible. After this, discussions were held on the proposals by some member countries to revise certain OP and rules. The JWES proposal was largely approved.The Task Force Working Groups A (Documentation), B (Training and Education), C (Inspection and Auditing), and D (Manpower Optimization System: MOS) then made reports regarding the AWF CWCS implementation plans. These were followed by more detailed reports on the plans by Japan and India, after which member countries made additional reports on their progress with MOS.In the next session, which was dedicated to the Second Task Force Session

on Standardization, Naoki Suzuki (Kobe Steel Ltd.), an auditor with the Welding Consumables Division of the JWES, made a presentation titled “How Japan Matched ISO Standards with its National Standards.” Using the specific example of ISO 2560:2009 (on covered electrodes for arc welding), he discussed Japan’s efforts to match standards and highlighted the need for common standards in Asia; this was all in the context that this task force should be used as a forum for sharing information about standards relating to welding materials, as well as for compiling the views of Asia and form proposals to feedback to the ISO. In addition, Mr. Lee of Beijing University of Technology spoke about standardization in China, specifically, welding materials in China and the standards that are applied to them.A notable feature of the present meeting was that senior representatives of the American Welding Society (AWS)—President Nancy Cole, Executive Director Ray Shook, and Corporate Director Jeff Kamentz—were attending the AWF task force session for the first time. In an address to the meeting, Mr. Shook said that the AWS is providing articles for each issue of Welding Promenade, the journal published by Sanpo Publications Inc., and that it is also collaborating with Sanpo Publications Inc. on promoting the development and diffusion of welding technology in Asia, as well as planning various events. He also expressed pleasure in participating in the AWF meeting and stated his his hope that the AWS and AWF can work together to establish a close and cooperative relationship.The AWF then made a presentation on the CWCS to the AWS representatives. There was some discussion about the differences in rules with the AWS system and proposals were made on how to bridge or eliminate these differences.On the following day, July 12, the AWF General Assembly was held. Since the current chairing country, South Korea,

was absent from the meeting, the former President of AWF Achdiat Atmawinata (President of the Indonesian Welding Society: IWS) gave the opening address. He then thanked the Singapore Welding Society (SWS), for hosting the meeting and expressed his appreciation for the efforts of the task force members. Next, the new President of SWS, Sze Thiam Siong, gave a welcome address as a host country spokesman. He spoke of his hope for the success of the AWF’s efforts to achieve common standards in Asia and offered a prayer that the AWF’s initiatives would proceed smoothly and fruitfully.The proceedings of the General Assembly featured reports on the results of the previous day’s task force session and reports on the CWCS and MOS implementation plans of each member country. The IWS then gave a report on the launch of the AWF website, with some discussion about the content of the site and its website address. This was followed by a Institute of Materials Malaysia (IMM) presentation on an international conference and exhibition on the theme of materials, “ I M T E C 2 0 1 4 ” , which is scheduled to be held in Kuala Lumpur over four days from May 13 to 16 of next year. It was unanimously decided that the AWF will co-sponsor the event.Finally, it was formally resolved that the next AWF Task Force Meeting and General Assembly will be held concurrently with the Japan International Welding Show 2014, over two days, April 23 and 24 of next year, at Tokyo Big Sight.

The Beijing Essen Welding & Cutting Fair 2013 (BEW2013)

skyrocketing development has been particularly

striking over the past few years. This year’s fair was

the biggest ever.

The event venue was spread across of eight halls at

the SNIEC: three in the East Block (E5 to E7) and five

in the North Block (N1 to N5). The total exhibition

space was approximately the same as the previous

Shanghai BEW, but there were 98 more enterprises

exhibiting at the most recent fair. The total number

of international (non-Chinese) exhibitors rose to

208. Some of the regular Western companies in

The Beijing Essen Welding &

Cutting Fair 2013 (BEW2013)

unfolded on a massive scale at the

Shanghai New International Expo

Center (SNIEC) over four days, from

June 18 to 21, marking the 18th

time this event was held. Despite the

general economic slowdown that

has arisen since the Shanghai Expo

of 2010, the huge market in China

attracted its normal high level of

interest from around the world, with

large numbers of visitors packing

the venue. Many of the attendees

were at least partially enticed by

expectations of economic stimulus

measures from the new Chinese

government.

The BEW location alternates each

year between Beijing and Shanghai.

According to organizers, this year’

s Shanghai venue boasted a total

exhibit ion space of 96,200 m2

and attracted a total of 1,016

exh ib i to r s f rom 28 d i f f e ren t

countries, including many of the

world’s leading manufacturers,

each drawn by China’s huge and

lucrative market and undeterred by the economic

downturn. Chinese manufacturers were also

present, demonstrating remarkable technological

advancements and showcasing products under their

own brands with growing confidence, thus bringing

additional liveliness to the fair.

The opening day drew a total of 10,883 people, and

attendance was excellent on the second day as well,

with vibrant activity continuing unabated throughout

the rest of the event. For well over 10 years now,

the BEW has steadily grown in scale, but the fair’s

attendance included Lincoln and Miller, as well as

ABB, Kuka, Hypertherm, Fronius, Kemppi, Messer, Air

Liquide, and Cloos – all of which displayed large and

attractive booths.

While international manufacturers like South Korea’s

Hyundai Welding and Kiswel competed for the most

spectacular displays, Chinese makers showed off

their brand-name products in a variety of categories,

including welding equipment, welding consumables,

and cutting equipment. Although Chinese brands had

previously lagged behind internationally recognized

foreign products in terms of quality and features,

the locally manufactured products on display at

this fair seemed to be in the same league as their

industry-leading Japanese and Western counterparts.

The remarkable advancements in the technological

capability of Chinese manufacturers were one of the

outstanding features of this year’s event.

Many of the welding power supplies on display

at the fair – most of them produced by Japanese

and Western manufacturers – were of the high-

performance and high value-added type. A similar

trend was evident in the displays of Chinese

manufacturers, which clearly reflects a dramatic

change in demand within China’s domestic market.

Exhibitions of automatic equipment and welding

and handling robots were also quite notable, both in

terms of popularity and number, probably as a result

of the rapid rise in labor costs being experienced in

China’s major cities (more than 10% per year) and

Regular exhibitors made their presence felt with large exhibition booths.


a growing shortage of young workers available

for factory employment. There was also evidence

of evolving demand for the higher quality and

increased productivity that increased automation

can provide.

In the area of welding consumables, the bulk

of exhibitors were South Korean and Chinese

companies, with manufacturers showing off broad

lineups of solid wire, flux-cored welding wire (FCW),

and other products. These wares were primarily

aimed at customers in the automobile manufacturing,

shipbuilding, and offshore industries. In the area

of cutting equipment, where plasma cutters are

now the mainstream, Japanese companies attracted

significant interest in their laser oscillator-based

cutters and fiber laser processors, and are now seen

to be pioneering a widespread diffusion of laser

cutting technology into the Chinese market.

Visiting Former Interns in Indonesia

The “Scheme for Training of Foreigners in Japan” is a system that aims at making an international

contribution to developing countries and promoting international cooperation by helping foreigners to acquire Japanese technology, skills, and knowledge. The foreign trainees are sent to Japan by a private or public sending organization in their home country. In Japan, they are hosted by a Japanese company or organization that undertakes their training.

In 2004, Welding Al loys Japan (WAJ) Ltd., a company that per forms abras ion -res is tant and corros ion-resistant welding and deals in sales of welding consumables ( f l u x - c o r e d w i r e ) a n d automated welding systems began host ing t ra inees/interns from Indonesia. Over the next eight years, the company hosted a total of seven Indonesian trainees/

interns.In July 2012, the last of the seven interns (Mr. Jaenal Nasuh) returned home to Indonesia. In December of 2012, the president of the company, Toshi-ichi Aota, visited Indonesia, where he travelled to meet up with five of the seven interns that had worked at WAJ. He even visited three of the former interns at their homes. This report describes the reunion of WAJ president Mr. Aota with those former WAJ interns.1. Accepted trainees/internsThe seven Indonesian trainees/interns hosted by WAJ, along with details of their stays in Japan, are as follows:

① Mr. Arif Rahman Syah Maulana (born 5/2/1983)3 years from 5/1/2004 ② Mr. Amir Mahmud(born 10/29/1984) 3 years from 5/1/2004 ③ Mr. Akmal Musodik (born 2/17/1985)3 years from 4/1/2006 ④ Mr. Okeu Nugroho Susanto (born 2/26/1985)

3 years from 5/2/2007 ⑤ Mr. Muhamad Biron Fikri (born 12/30/1986) 3 years from 4/16/2008 ⑥ Mr. Suprianto (born 2/3/1987)3 years from 12/16/2008 ⑦ Mr. Jaenal Nasuh (born 8/19/1989)3 years from 7/27/2009

2. Current work/employment statusThe work/employment status of each of the seven interns (as of Dec. 2012) is given below:

① Mr. Arif: Factory manager of a welding fabrication company ② Mr. Amir: Company sales executive (Pt. Abrasive Material Prima) ③ Mr. Akmal: Launched his own company to manufacture and sell ornaments/accessories and is now developing it.④ Mr. Okeu: Staff member of a start-up company, Pt. Trim Rubber (in Cikaran) (Trim Rubber is an Indonesian joint venture company of Tokyo Rubber MFG. Co., Ltd.) ⑤ Mr. Biron: Employed by Koito Industries Ltd. in Indonesia⑥ Mr. Suprianto: Studying at university ⑦ Mr. Jaenal: Expecting to join Daiichi Jitsugyo Ltd. in Indonesia

Note that Mr. Aota was informed in advance by Mr. Biron and Mr. Suprianto that they would not be able to meet up with him (as well as by Mr. Okeu).3. Reunion in Indonesia3.1 December 22

Garuda Indonesia flight GA 867/N from Thailand to Jakarta touched down at 5:45 p.m. as scheduled. Mr. Okeu, Mr. Akmal, and Mr. Jaenal had all traveled from various locations to Jakarta to welcome Mr. Aota on his arrival.

The plan for the day was to drive Mr. Aota by car to

Cikaran and to meet up there with Mr. Arif and Mr. Amir, both of whom are from Jakarta. The six men would then all dine together and update Mr. Aota about

what they have been doing. The journey from Jakarta to Cikaran was plagued by traffic worse than that of the Tokyo Metropolitan Expressway, so by the time they arrived in Cikaran it was 10:30 p.m. Since there were no restaurants open at this hour, the group had to retreat to a bar-style venue called “Jun”, where they chatted nostalgically and energetically. Photo 1 captures a moment from this gathering.Mr. Aota inferred that Mr. Arif must have been doing quite tough physical work, judging by the state of his shoulder muscles, which rippled through his shirt. Mr. Amir seemed to be working late every day, often also entertaining clients at night. As a result, he was close to 80 kg in weight. Mr. Aota advised him to try and lose weight by the time they meet next. “Hai” was Mr. Amir’s response.3.2 December 23On the night of December 22, Mr. Aota stayed at a first-class hotel in Cikaran, as arranged by Mr. Okeu. This day’s itinerary was very full and included the following:

(1)Visit to Sukabumi(2)Tour of Mr. Okeu’s apartment(3)Visit to the home of Mr. Jaenal(4)Meeting with Ms. Meta. Ms. Meta was a trainee/intern at WAJ in Saitama. She now works at Trim Rubber.(5)Visit to the family home of Mr. Okeu(6)Dinner with the family of Mr. Akmal

(1) Mr. Okeu’s apartment, tour of Trim Rubber, and visit to Mr. Jaenal’s homeAt about 8:30 a.m., Mr. Aota left the hotel together with Mr. Akmal, Mr. Okeu, and Mr. Jaenal. The first stop for the group of four was Mr. Okeu’s rented apartment, where Mr. Aota was able to meet Mrs. Okeu (Mr. Okeu’s wife) and the couple’s six month-old baby. (Photo 2) N e x t u p w a s a t o u r o f Tr i m Ru b b e r ( a n Indonesian joint venture company with Tokyo Rubber Mfg. Co., Ltd.), w h e r e M r . O k e u i s emp loyed . Mr . Ao ta w as imp r e s s e d t ha t the premises appeared as neat and orderly as those of a factory in Japan. Currently there is a team of approximately 15 employees working under Mr. Kawamura, the company president, in preparation for launching a manufacturing operation in Indonesia. Mr. Aota noted that Mr. Okeu seemed to be acting as the team leader and organizer and was very pleased to learn that he was still independently making use of many things that he had learned at WAJ in Japan—such as the daily morning meeting, the practice of “KY” (kiken yochi = “predicting dangers”), and the 5 S’s (a set of five methodology principles for executing business, each starting with the letter “S” in Japanese: seiri (sorting), seiton (straightening), seisou (cleaning), seiketsu (cleanliness), and shitsuke (discipline)—and that he had earned the trust of Mr. Kawamura.Mr. Aota was next taken for a visit to the home of Mr. Jaenal. (Photo 3) All the members of Mr. Jaenal’s family welcomed Mr. Aota and urged him to enjoy some Indonesian refreshments. Although it was explained that Mr. Jaenal’s father was not able to perform strenuous work due to his poor health, he looked well on that day and had a ready smile. His mother, on the other hand, was a little tense. However, Mr. Aota felt that she would

soon reveal a friendly personality if he were to spend little more time with her.(2) Visit to the home of Ms. MetaMs. Meta apparently spent three years as a Japan Indonesia Association for Economy Cooperation (JIAEC) trainee/intern at a die-casting company in Saitama. After returning to Indonesia, she was introduced to Trim Rubber and is now working there together with Mr. Okeu. According to Mr. Okeu, Ms. Meta is capable of doing tremendous work. Ms. Meta’s home is located a couple of houses in from the street. At the entrance way, her mother came out to greet the group. From the warm welcome he was given, Mr. Aota received a sense of Ms. Meta’s natural tendency to be well prepared. She was just as he had imagined her, and he enjoyed her company on that day.(3) Visit to Mr. Okeu’s homeThe next stop was a visit to the home of Mr. Okeu. (Photo 4) Mr. Aota was welcomed by Mr. Okeu’s cheerful mother. His father, who was coming down with a cold, seemed a little stiff at first, but soon beamed with a welcoming smile. Mr. Okeu’s grandmother also had a distinguished air about her. Mr. Aota was presented with a home-made delicacy.(4) Dinner with the family of Mr. AkmalDinner with Mr. Akmal’s family was at a restaurant close to their home. Including Ms. Meta and Mr. Akmal’s firstborn child, there were 10 people in attendance. (Photo 5) Mr. Akmal’s family also seemed a little tense at first, but thanks to good humor of Mrs, Yati (Mr. Akmal’s wife), the atmosphere soon lightened up. Mr. Aota sensed that Mr. Akmal was leading a happy life and working hard to further improve his current standing.3.3 December 24Mr. Okeu organized this day’s schedule. On the itinerary were a visit to the company Pt. B. J. Mandari, where Mr. Okeu’s uncle is an executive, as well as a tour of a factory where white mushrooms are cultivated.Pt. B. J. Mandari (Photo 6) receives orders from Japanese parts makers for Honda, Yamaha, and other Japanese-brand motorbikes. It even manufactures some of the parts (e.g., brakes) itself using processes such as cutting, casting, and welding. In the past several years, the company has grown rapidly and it now employs approximately 100 people. Mr. Aota felt that the 3 S’s (a set of three methodology principles for executing business, each starting with the letter “S” in Japanese: seiri (sorting), seiton (straightening), and seisou (cleaning)) were being observed well at the factory.The group then left to tour a white mushroom factory run by another relative of Mr. Okeu.At this point, all the scheduled visits were completed. To conclude the trip, everyone gathered to have a final lunch together before heading off to Jakarta’s international airport. On one section of the road to Jakarta, traffic was so congested that the car could move no faster than walking pace. At the airport, the group ate dinner. Considering their long drive home,

Mr. Aota urged the group to head back, but they did not want to leave. The three hours together felt very short. And, at the moment of separation, Mr. Aota detected a certain wistful sadness in the eyes of his former interns.4. ConclusionDuring his visit to Indonesia, Mr. Aota was able to meet some, but not all, of the people he hosted in Japan. His overal l impression was that all of his Indonesian friends were facing challenges in work and life, but also that t h e y w e r e f a c i n g these challenges with great determination. They will probably c o n t i n u e t o f a c e various challenges in the future, but maybe at moments of particular difficulty they will remember something that Mr. Aota said to them, something that might give them some inspiration to push ahead. And, even if the encounters between Mr. Aota and his Indonesian friends do not amount to much in the grand scheme of things, hopefully they contribute in some small way to greater understanding between Japanese and Indonesians.That would make Mr. Aota happy.Mr. Aota was glad to meet his former Indonesian interns again: Mr. Arif, who is gentle, simple, and strong;

Mr. Amir, who is shrewd yet childlike; the serious Mr. Akmal, who is hard on himself; Mr. Okeu, who is so considerate to others around him and who could easily be a first-rate entertainer; Mr. Biron, who, following in the footsteps of Mr. Akmal, volunteered for a Japanese-language speech contest and spoke impressively in the presence of the mayor of Saitama; the serious Mr. Suprianto, who is so devoted to his parents; and the mischievous but cheerful Mr. Jaenal.

The 7th Asia Pacific IIW International Congress was held from July 8 to 10, at the Administration

Bui lding, Singapore Management University in Singapore.The opening ceremony began with a welcome address by Ang Chee Peng, the former president of the

Singapore Welding Society (SWS), as seen in Photo 1.

This international congress was reported to include approximately 100 research presentations and nine poster presentations from some 35 different countries, which showcased the very latest technological developments in the fields of welding and jointing. The event also aimed at effectively promoting the exchange of knowledge.During a congress exhibition held on the 4th floor of the building, Mr. Ang expressed gratitude for the support of the 10 companies that co-sponsored the event. Finally, he also mentioned that the opening date of July 8 was selected because it is considered auspicious by Chinese people.Welding is an essential technology in a wide range of industries. It is especially vital in shipbuilding. The congress was designed to foster discussion on topics such as innovations in welding technology, welding product quality improvement, increasing the useful life of welded products, training of welders and other welding personnel, and improvements to education, with the sincere hope that such discussion proves fruitful. Next, IIW Communications Manager, Ms. Lisa Busby-

Montenegro presented an outline of International Institute of Welding (IIW) activities. This was followed by the Jaeger Lecture (the introductory lecture of every IIW Regional Congress), which was delivered by Mr. Ho Siong Hin, Divisional Director, Occupational Safety & Health Division of the Singapore Ministry of Manpower.Of the various technology lectures the four below were designated as keynote presentations:

(1) IIW Guidelines for Increasing the Fatigue Strength of Steel Under High Cyclic Loading (G. B. Marquis)

(2) Control of Welding Technique Based on Modeling the Sensitivity of Welders (Y. M. Zhang)

(3) Welding Methods for Dissimilar Metal Joints of Titanium Alloy, Stainless Steel, and Carbon Steel (Ngai-Mun Chow)

(4) IIW White Paper (Chris Smallbone) (Photo 2)Approximately 300 people from 35 different countries, mostly in Asia, attended this year’s international congress, which featured presentations and discussions on the state of welding technology in the attendee’s respective nations.Compared to 15 years ago, the level and standard of welding technology in Asian countries has risen

dramatically. Over this time, welding societies have become established in many countries and significant amounts of effort have been poured into research and development. Since the Asian Welding Federation (AWF) was founded in 2004, this trend has grown increasingly stronger. This fact is immediately evident to anyone who reads the content of the papers presented at the congress.To provide an outline of the research topics that were

A non-des t ruc t i ve t e s t i ng (NDT ) s emina r f o r infrastructure, jointly organized by the Singapore

government and Japan’s Ministry of Land, Infrastructure and Transport (MLIT) was held on August 2 at the Singapore EXPO Convention and Exhibition Centre. The seminar addressed issues related to NDT technology for infrastructure-related systems, as cultivated by private Japanese companies. In view of Singapore’s increased demand for infrastructure-related services expected in coming years, the seminar was designed to promote awareness of the advantages provided by NDT technology to Singaporean government officials and relevant contractors, as well as to promote more widespread adoption of the technology.As the sole non-governmental partner, the Japanese Association for Non-Destructive Testing Industry joined in the planning of the NDT seminar at the request of the Policy Bureau of Japan’s MLIT. The seminar was held concurrently with an exhibition held as part of the Singapore Construction Productivity Week campaign organized by Singapore’s government. On the day of the NDT seminar, some 70 interested persons from Singapore and neighboring countries packed a venue that had an official capacity of just 50. Before the opening of the seminar, the Deputy Vice-Minister for Construction, Engineering and Real Estate Industry of the Minister’s Secretariat at Japan’s MLIT, Shin Honto, gave an opening address. Mr. Honto described Singapore as a highly valued partner in the economic development of Southeast Asia over many years, as well as the most vital base for the neighboring region, and said he expects to see continued vigorous demand for infrastructure in the coming years as Singapore’s current phase of rapid economic growth continues. Mr. Honto then stated that Japan’s government and industry can play an important role in this regional development by clearly transmitting the wealth of infrastructure-related technology accumulated by the Japanese construction industry to the nation of Singapore, and more broadly to the Southeast Asia region.Finally, Mr. Honto explained that the seminar would include presentations about how NDT technology can be used to increase efficiency and reduce costs related to

infrastructure maintenance and renewal, as well as case studies gleaned from the various company experiences, proposals of possible applications in Singapore, and an outline of the latest available NDT technology. He also expressed his conviction that NDT can be used effectively

to maintain and renew soft infrastructure that has already been built.Yasuto Matsumura, Chairman of the Japanese Association for Non-Destructive Testing Industry then spoke a few words. “Along with the striking economic development we are seeing in Singapore, there are also many efforts to improve infrastructure. Here, we want to show you some maintenance techniques developed in Japan that utilize NDT as a way of maintaining infrastructure more safely and securely.”The seminar featured four sessions:

•“Maintenance Management System Using MIMM” (Jang Sobyong of Keisokukensa Co., Ltd.)•“Automatic Ultrasonic Inspection System for Railway Axle” (Tsuguki Nishioka of KJTD Co., Ltd.)•“About New Generation Concrete Radar” (Tadashi Sato of Japan Radio Co., Ltd.)•“Non-destructive inspection of civil engineering structures using radar” (Yasunari Mori of Mitsui Engineering & Shipbuilding Co., Ltd.). Each of the sessions concluded with a lively exchange of questions and answers.

Note

Indonesia has achieved a rapid rate of economic growth over recent years. In addition to the enlargement of the nation’

s affluent classes, the era of widespread private automobile ownership has finally arrived. In 2012, automobile sales in Indonesia totaled 1,116,230 units (up 24.8% over the previous year), breaking the previous year’s annual sales record for the third year running. Furthermore, with sales predicted to grow to 1.5 million by 2015, and to 2.0 million by 2020, Indonesia is poised to become the largest single automobile market in the ASEAN region. Remarkably, Japanese automobile and motorcycle manufacturers (and their subsidiaries) are reported to account for over 95% of this market.In view of this, all Japanese automobile makers are working to establish new Indonesian manufacturing plants while simultaneously actively investing in new plants and equipment to boost their local production capacity. In concert with these developments, international parts suppliers are advancing into Indonesia one after another, and the pace is only expected to accelerate in the years ahead.At the same time, massive projects to build or expand infrastructure in the suburbs of the capitol city of Jakarta are proceeding at fever pitch, and there is a flurry of efforts to boost the number and kinds of high-speed ferries and cargo vessels used to transport people and resources between the numerous islands of the nation. Amid such circumstances, there can be little doubt that Indonesia is fast becoming a highly alluring market for welding equipment and welding robots.As this market matures, the suppliers handling the various kinds of tools, equipment, and industrial products that are indispensable for manufacturing are enjoying similar growth as well. Young entrepreneurs and company employees in Indonesia are showing levels of vitality and business passion, and above all a firm self-confidence, that is comparable to that seen during Japan’s high-economic growth period and in the fast-growing economies of China and Thailand. One example of this energy is Pt. Sinar Buana, a fast-growing Indonesian company that we recently visited.The company was launched in 2002 by then 38-year-old Mr. Harjadi. Its current head office is in the West Jakarta district, where it now employs a total of 34 employees. Pt. Sinar Buana positions itself as a trading company specializing in tools and machinery. In the 10 years since it began operating, the company has developed a sales zone centered on Jakarta in which it offers excellent tools, machinery, and industrial materials imported from a wide range of countries. Although only of medium scale, it practices a rock-solid approach to management and has earned lasting trust of its customers and suppliers.In the area of welding equipment, Pt. Sinar Buana has built a broad network of connections with manufacturers for a wide variety of welding equipment, most notably OTC in Japan and Italy’s Cebora S.p.A., but also makers from South Korea, China, Thailand, and Malaysia. The array of products it handles is truly diverse, and includes all kinds of welding supplies and consumables such as welding torches, parts, gas regulators, gas cutting nozzles, and grindstones, all with the exceptional performance, quality, and cost competitiveness needed to meet the demands of its customers.On top of all this, another great strength of the company is

that, since its founding, it has sold various kinds of cemented carbide tools as an agent of the Japanese company Kyocera Corp. The fact that it has been able to trade in these high-priced consumables, which can cost hundreds of dollars apiece, has contributed substantially to stabilizing the company’s business. As president, Mr. Harjadi is proud that the company has grown steadily and smoothly over the 10 business years since its founding. Growth has been particularly strong in the past few years, with total sales growing at 20 to 25% annually. In 2012 alone, sales of welding equipment were up more than 30% over the previous year.Much like its sales, Pt. Sinar Buana itself has grown steadily over the years and last year, due to the expanded scale of its business, finally relocated from its former cramped head office to a new office complex. The second floor of the company’s two-level head office building contains a fully computerized, attentively designed office space and meeting room. The first floor, on the other hand, is devoted to product warehouse space, maintenance, and delivery areas. The vision behind the headquarters design was to provide sufficient space to ensure a good ready stock of products, while simultaneously setting up a system to enable staff to work independently, at least to some degree, on the maintenance of welding equipment and other products.As for the cemented carbide tools produced by Kyocera Corp., which are the company’s main products, space has been provided for a ready stock of more than 2,000 items. Furthermore, the company has developed a system that allows rapid response to orders from customers, all backed by stringent security measures.In the words of Mr. Harjadi, “As a trading company, we deal in products from many different countries in order to flexibly meet the needs of our customers. Up to now, our sales growth has centered on welding equipment. However, we are convinced that in the years ahead, as the wages of workers increase and as more importance is placed on stable welding quality, higher performance, and efficiency, the demand for welding robot systems is going to grow widely among local companies in Indonesia. We are thinking of investing effort in selling robot systems in the future. In this sense, the Factory Automation Center opened last April by one of our main customers, OTC Indonesia, is very valuable as a sales resource for us and as a center both for product users, because it allows all kinds of demonstrations, work tests, and trials to be performed. We look forward to the improvement in OTC’s total support preparedness as a result of their enhanced service capabilities and upgraded inventory capacity.”Mr. Harjadi pointed out that in the current Indonesian market, when it comes to thin plate for automobile and motorbike manufacturing and other applications where high-quality welding is demanded, the products of Japanese companies are overwhelmingly dominant, both in the case of welding equipment and welding robots. On the other hand, in the area of shipbuilding, where demand is more focused on durability and high output, the market is being closely contested between Western, Chinese, and South Korean manufacturers. Mr. Harjadi said that, “Based on a careful analysis of these market trends and demands, we plan to develop our business according to an original optimized sales strategy and product availability.”

Q We are very interested in brazing titanium products. My question concerns brazing titanium with steel. Basically, we would like to join titanium Grade 5 plate with stainless steel 304 round bars (1 or 7⁄8 in. in diameter) and require a strength of 40 ksi at the joint. Please suggest a suitable filler metal and a brazing process for us to try.

A Technically, vacuum brazing of titanium Grade 5 (Ti-6Al-4V alloy) to stainless steel is not a problem. The process of joining titanium to nickel-plated stainless steel using a silver-copper eutectic (AWS BAg-8) as a brazing filler metal has a long history of industrial application, and has been studied rather thoroughly (Ref. 1). The brazing is carried out over a wide temperature range from 820 ° to 920 °C depending on the design of joined parts and the required joint strength. BAg-8a — the lithium-modified BAg-8 filler metal — can also be used in the same range of brazing temperatures. The brazed parts are shown in Fig. 1. BAg-8a is not suitable for vacuum brazing, unless the heating rate is so high that it takes only 1 to 2 min. to reach the brazing temperature. So, this braze is ideal for induction brazing or brazing by energy beam (electron or laser). Within the last two decades, new processes and material options have been studied and tested. The application of new titanium flux RL3 A16 opened the opportunity to join titanium to titanium and titanium to steel in air using torch brazing or, preferably, induction brazing. Standard silver-based filler metals such as BAg-24 or BAg-34 are successfully used for brazing in air. A key point of this process is rapid and uniform heating of the joint area, because titanium oxidizes very fast and the protection ability of flux is limited in time. Therefore, brazing in air is successful mostly for small-size parts. Precoating the titanium part before brazing is recommended. This means that you should use a three-step process: 1) deposition of the silver braze alloy onto the titanium surface by heating and melting with the flux, 2) removing flux residues from the surface using hot water and a metal brush, and 3) assembling with the steel part and brazing them together with new additions of flux and braze filler metal. The joint clearance between the parts to be brazed should be as small as possible due to the difference of coefficients of thermal expansion. With your design, this means that you should slightly compress the parts during brazing and cooling. Brazing titanium to steel can also be done in air with the same flux and aluminum-based filler metal TiBrazeAl-635 (the Al-Cu-Mg system) or TiBrazeAl-655 (the Al-Cu system) at a temperature below 700 °C — Fig. 2. The aluminum filler metals can be used, when a low brazing temperature is needed, while the strength of joints is not a critical issue. However, vacuum brazing with BAg-8 is still the most often used process for joining titanium to stainless steel. In order to reach the maximum strength of the brazed joint, the brazing should be done in compliance with the recommendations below. First, the stainless steel should be plated with nickel 0.0004 to 0.0006 in. (10 to 15 microns) thick. Nickel plating significantly improves the spreading of liquid filler metal along the steel surface. Sometimes, electroless nickel plating does not provide a stable quality of coating. Then, silver plating 0.0006 ± 0.0001 in. (12 to

15 microns) thick is used instead of a nickel coating. The nickel or silver layer serves as an effective barrier to prevent the formation of brittle Ti-Fe intermetallics that are replaced by NiTi, AgTi, and CuNiTi phases. Second, the brazing temperature in the range of 830° to 850°C and dwell time from 3 to 6 min are optimal process parameters to produce 25 to 30 ksi (170 to 210 MPa) joint shear strength. Higher brazing temperature and longer holding time result in uncontrolled growth of the brittle TiCu2 intermetallic layer at the interface of the joint metal with titanium, and the strength of the joints goes down to 20 ksi (140 MPa) or even lower values. If you want to increase the strength of the joints to 40 ksi (275 MPa) and higher, you will have to change the joint design. For example, use a tube-in-tube design instead of a simple overlapping, or provide so-called mechanical securing of brazed joints, such as brazing of a threaded connection.
