Transport

9 Electromagnetic compatibility (EMC)

This product is manufactured in conformance with the current EMC standard. Please note the following:

D Due to their high power consumption, welding ma­chines can cause problems in the public power grid. The mains connection is therefore subject to require­ments with regard to the maximum permissible sys­tem impedance. The maximum permissible system impedance (Zmax) of the interface to the power grid (mains connection) is indicated in the technical data. If in doubt, please contact your power grid operator.

D The machine is intended for we lding in both commer­cial and industrial applications (CISPR 11 class A) . Use in other surroundings (for example in residential areas) may disturb other electronic devices.

D Electromagnetic problems during start-up can arise in:

- Mains cables, control cables, signal and telecom-munication lines near the welding or cutting area

- TV/radio transmitters/receivers

- Computers and other control devices

- Protection equipment such as alarm systems

- Pacemakers and hearing aids

- Measurement and calibration devices

- Equipment with too little protection against inter-ference

If other equipment is disturbed, it may be necessary to provide addit ional shielding.

D The affected area may go beyond the boundaries of the property concerned. This depends on the layout of the building , and the other activities that may be going on there.

Please use the machine in compliance with the manu­facturer's instructions. The operator of the equipment is responsible for the installation and use of the machine. Furthermore, the owner is responsible (if necessary with technical assistance from the manufacturer) for eliminat­ing the interference caused by electromagnetic fields.

10 Transport For transport using mechanical lifting gear (e.g. cranes etc.) only the handle may be used as the hoisting point. Use suitable load-bearing equipment. Do not use a fork-l ift 1ruck or similar de­vice to lift the machine by its housing. The carrying strap is exclusively for the transport by a person.

15 Welding basics

15.1 Stick elect rode welding <--- ----Coated stick electrodes are used for the widely-used manual metal arc welding process (stick electrode weld­ing). The coating of the electrode melts off during the welding process together with the core wire. The coating generates the shielding gas. Additionally the burning­off coating compensates alloy elements. which are de­stroyed in the molten pool. A slag layer forms on top of the welding seam. which covers and protects the cooling welding seam against the air.

The coatings of the electrodes differ according to thick­ness and type, i.e. chemical composition. This results in different welding properties and consequently different applications for the e'lectrodes. Types and nomenclature are defined in DIN EN 499 (formerly 1913).

-'--- Stick electrode

Base metal

15.2 TIG welding

The TIG welding process is a universally-applicable pro­cess which creates high quality joints.

The electrode of the TIG process consists of non-melting tungsten, the shielding gas is an inert gas. In English usage we speak ofTIG welding ("Tungsten" = Wolfram).

Inert gas is chemically neutral and does not react with the weld metal. Inert gases are, e.g. argon, helium and their mixtures. Usually pure argon (99.9%) is used. The welding gas must be dry. DIN 32 526 defines the differ­ent types of shielding gas.

TIG welding process bas ics A non-melting tungsten electrode is clamped with a col­let into a gas or water-cooled torch . The arc burns be­tween the tungsten electrode and the workpiece in an inert shielding gas atmosphere. Thus the tungsten elec­trode acts as an arc carrier. The arc melts the workpiece point by point and forms the weld pool. The shielding gas escapes through the gas nozzle. This gas protects the tungsten electrode, the arc and the molten pool against the surrounding air. This prevents undesired oxidation. Consequently, poor welding results may occur due to trouble with the shielding gas supply.

In case additional filler material is required. filler ~1\re is supplied either manually, as in gas name welding, or

-18 -

Welding basics

automatically by means of a cold wire feeder. The filler wire must be equally or more highly alloyed than the base material. Flange and corner welds can be created easily without filler wire.

Shielding gas

Basically, both DC and AC may be used for TIG welding. The current mode and polarity depend on the material to be welded.

Non or low-alloyed steel, high-alloyed steel and copper, as well as titanium and tantalum are welded with DC. The electrode is connected at the minus pole because of the stronger current loading.

When welding aluminium and nnagnesium as well as their alloys, AC must be used in order to tear up the high­melting and tough oxide skin which forms on the molten pool or which is present on the base metal. If the oxide skin is missing. e.g. there has been welding on the same part for a longer time, the arc can be unstable or break up from time to time.

Shape of the electrode tip Tungsten electrodes always have to be ground length­wise because crosswise grinding marks cause an un­steady arc.

LORCH The shape of the electrode for DC welding has to be and remain as sharp as a pencil. The angle of the point depends on the welding current. When AC welding, ii is sufficient to sharpen the edge of the electrode slightly. After a short time, a round to slightly convex form is built.

If the electrode tip is polluted due to dipping into the weld pool or touching the filler wire, the respective part of the electrode must be completely ground off. Restore the original, pointed shape. Grind in longitudinal direction.

LORCH Fundamentals of the MIG/MAG welding process

16 Fundamentals of the MIG/MAG welding process -~"'--'"~~~~~~~~~~~~~~~~

16.1 Principle of the MIG/MAG welding process

The wire feed rollers feed the wire electrode from the reel to the contact tip. An arc is created between the wire electrode and the workpiece. The wire electrode thus becomes the arc carrier. The arc melts the workpiece point by point and forms the weld pool. The wire elec­trode melts and drips into the weld pool, thus forming the filler metal. The inert gas flows from the gas nozzle and protects the arc and weld pool from atmospheric gases.

There are two types of metal shielding-gas welding that are differentiated by the type of shielding gas that is used: metal inert gas welding (MIG), inert shielding gas) and metal active gas welding (MAG, active shield­ing gas).

MAG-M Mixtures of Ar/ C02Ar/02

Tab. 7: MIG/MAG welding processes

The welding processes are further differentiated by arc type. This means that there are differences in the form of the arc, short circuit tendency and metal transfer mode.

Selection of the type of arc is only possible to a limited extent e. g. when short arc welding. Short arc welding is possible using all metal shielding gas welding processes by the selection of the suitable current intensity and the associated arc voltage, although the short circuit fre­quency and drop size are very different, according to the shielding gas being used.

- 20 -

16.2 Arc types

Short arc This type of arc is particularly suited to the welding of thin sheets, in root layers and for welding in restricted locations because of its relatively "cold" weld flow. In this case, the welding takes place with a very short arc. at low arc voltage and at low current intensity. Due to the surface tension of the melt pool, the drop is drawn into the molten metal and the arc is reignited. This recurring cycle creates a continuous alternation between the short circuit and the arcing period.

CD The transition from short to spray arc is de­pendent upon the gas mixture and the wire diameter.

Transition arc A transition arc is used for medium plate thickness and for vertical down welds. The material transfer tales place both in short circuit and in free flow. This produces a re­duced short circuit index and a slightly "hotter" molten pool than in the short arc. Transition arc welding has a higher melting rate than short arc, and is therefore more economical.

Long arc Long arcs are typically used for welding under carbon dioxide and under high C02 containing gas mixtures in the upper performance range. Long arc welding is not really suitable for welding in tight spaces. Larger drops fall into the molten pool largely by gravity. This some­times involves short circuits which, al the point or the short circuit, can produce spatter when the arc ignites again. because of the upslope.

Spray arc Due to the thinness of the melt pool, spray arc welding is not suitable for welding in tight spaces. It is used for welding in the higher power range using inert gases or gas mixtures with high argon content. The spray arc has a very fine drop, short-circuit free material transfer.

Tab. 8: Working ranges for MAG welding

Holding and guiding the torch

CD With metal shielding gas welding, you can

no work in all positions: level, horizontally, vertically from top to bottom, vertically from bottom to top, overhead and in lateral posi­tion.

For level and horizontal and level welds, hold the torch vertically (neutral torch position) or pushing at up to 30°. On thicker layers you can also drag the torch slightly. The neutral torch position produces the best penetration depth and inert gas coverage. Take care not to tilt the torch too much, otherwise air could be drawn into the inert gas shield by the injection effect.

If you are welding vertically and overhead then you should push the torch slightly. Down welds are used mainly for welding thin plates. In this case, hold the torch in as neutral or slightly dragging position. This technique requires specially trained and experienced welders , since there are dangers from incomplete fusion due to the forward melt pool. This danger increases with thicker materials, or if the melt pool is very thin because the volt­age is too high.

Weld direction pushing Weld direction dragging

Fig. 13: Torch position

Avoid larger oscillating movements in order to prevent the melt pool from building up in front of the arc. This can lead to incomplete fusion due to the forward melt pool. Except in the vertical up position. you should oscillate laterally only as far necessary to cover both edges of the

10.13

seam. If the seam is sufficiently wide, weld two beads alongside each other.

If you are welding in the vertical up position, your oscil la­tions should be in the shape of an open triangle.

Arc length The longer the arc. the shallower is the penetration depth, the wider and flatter the weld bead and the great­er the tendency to spatter. The weld metal is transferred in slightly larger drops compared with a shorter arc. Use a longer arc when fillet welding, in order to produce a flat or concave weld bead.

A shorter arc increases the penetration depth (at the same current intensity) , the weld bead is narrower and the tendency to spatter is reduced. The weld metal is transferred in finer drops until the short arc is reached.

Long arc Short arc

Fig. 14: Arc length

Electrode wire length In general, the distance between the torch and the work­piece is 10-12 times the wire diameter. You can also change the torch distance to affect the length of the free end of the electrode.

A longer free end of the electrode reduces the current intensity and the penetration depth.

A shorter free end of the electrode increases the current intensity while maintaining the same wire feed rate.
