21

ANNEXURE – C1

Specification for re-conditioning of worn out Points & Crossing, CMS Crossing and Switch

expansion joint.

1.0 Selection of worn out Points & Crossings, For re-conditioning

1.1 Condition:

Points and crossing to be re-conditioned by welding should be in good condition and certified by

the sectional Section Engineer Permanent Way for their suitability for re-conditioning and should

normally not exceeded specified limit of wear. Points and Crossings containing cracks on the

worn out portion having depth more than 3mm (as determined by gauging) beyond the

condemning size shall not be selected for further re-conditioning. Ultrasonic testing should be

carried out as per code of procedure to decide the serviceability. Points & Crossings having

internal defects should not be re-conditioned.

1.2 Wear limits

As far as maximum vertical wear limit on wing rails and nose of crossing is concerned, the

existing provision of 10mm vide 237(3) (e) of IRPWM will continue. However, on

Rajdhani/Shapahdi routes, as a good maintenance practice, crossings and the wing rails should be

planned for reconditioning before reaching the following wear limits.

Built up Crossings : 6mm

CMS Crossings : 8mm

(Ref: Rly Bd's Lr.No. 91/Track-III/TM/28 Dt. 12-1-1994

2. Various Resurfacing Techniques:

2.1 Single electrode technique

In this system of welding, only one type of electrode is used to make up for the entire worn-out

portion of the crossing. The worn out points & crossings can be resurfaced by this method by

gradually depositing number of layers as per requirements with 4mm dia electrode.

2.2 Depot resurfacing:

Points and crossings are usually brought from site to the welding depot and then they are

resurfaced following the conventional manual arc or continuous wire welding process using

transformer or rectifier. The reconditioned crossing is then ground, properly profiles and again

transported back to the site for re-use in track.

2.3 In-situ resurfacing

To avoid undue transportation as well as loss of man-power and time, in situ resurfacing can be

resorted to. In this technique, reconditioning of crossing can be done on track itself, after taking

block or only on caution order following the conventional arc welding techniques. For such in

site welding, portable DC welding generator is to be used, which can be carried easily to the

welding site.

2.4 Current practice:

2.4.1 As per the extent instructions of the Railway Board single Electrode System and

Continuous wire welding process will continue. No other process/system will be used without

specific and prior approval of RDSO. The welding process may be undertaken either at depot or

in situ as specified in the tender schedule.




22

2.4.2 Similarly, from the convenience point of view, it is preferable to resort to in situ

resurfacing techniques, specially, for built-up crossing, since transportation of crossings from site

to depot and back is avoided saving considerable time and effort. Moreover, it is also beneficial

in case of turnouts where heel/toe joints of switches and crossings have been welded with

lead/main line rails. In case of CMS crossings, the temperature is to be particularly controlled

during the welding process either by keeping the crossing submerged in a water bath or by

resorting to air quenching. Therefore, in situ reconditioning of CMS crossings will need

additional precaution.

3.0 Welding Electrodes:

3.1 Approved brands of electrodes:

H1and H2 class of electrodes has since been withdrawn for use in reconditioning of worn out

points and crossings by welding. Only H3C series of electrodes duly approved by RDSO are to

be used for this purpose. Electrodes manufactured by firms approved in current vendor list issued

by RDSO only shall be used in the reconditioning work. The above list is subject to the revision

every year by RDSO.

3.2 Class of electrodes used in respect of traffic density:

All electrodes now used for welding purposes fall under H3 series, though they have been further

classified into H3, H3A & H3B classes.

Based upon their traffic carrying capacity as detailed below:

(a) H3 Class to achieve minimum service life of 15GMT.

(b) H3 A Class to achieve minimum service lift of 25 GMT.

(c) H3 B Class to achieve minimum service life of 35 GMT.

(d) The class of electrode shall be as specified in the tender schedule.

4.0 Welder:

Only skilled of highly skilled welder who has been trained and certified by RDSO for

welding/recondition work holding a valid competency certificate shall be used for reconditioning

work. A copy of competency certificate with identity card should be lodged with SE/PW &

ADEN in-charge of work before commencement of the work.

5.0 List of equipment required for reconditioning.

5.1 For Crossing & Switches fabricated from 72 UTS or 90UTS rails.

6.0 Process of welding.

6.1 Medium Manganese steel or 90UTS Pts. & Xings (in depot):

6.2 Surface preparation:

The location to be reconditioned shall be ground by pneumatic or Electrical grinder to remove

adherent scales, deformed and work Hardened metal and surface cracks. Complete removal of

the surface cracks is necessary as any leftover crack on the surface may extend due to contraction

of the weld deposit during cooling and cause premature failure of the crossings in service. After

grinding the locations to be welded shall be tested by magnaflux or dye-penetrant methods to

ensure freedom from cracks.

6.3 Electrodes to be used and precautions taken.

Electrodes approved under H3 series of the approved list issued by RDSO shall only be used.

Low hydrogen type of electrodes shall be dried at 130 to 170 degree centigrade for at least one

hour immediately before use. Incase, the packing of electrodes is absolutely intact and all the

electrodes are consumed within 06(six) hours after opening of the packing, then pre-heating of

electrodes may be dispensed with. During use of this type of electrodes, care is to be taken to use

shortest possible arc and minimum weaving. Current polarity, angle of electrode and welding

technique as recommended by the manufacture of the electrode shall be used. Welding shall be

done using 4mm dia electrodes only to avoid high heat input. Electrodes having cracked and

damaged flux covering shall be discarded. The electrodes shall be stored in accordance with the

directions laid shown in para 11.2 of IS: 814-1994, the extract of which is appended below.

'11.2 Electrodes shall be suitable packed to guard against damage during transportation. The

packing shall be suitable to ensure that under normal store room conditions the electrodes shall

for period of at least 6 months after the dispatch from the manufacturer's stores, be capable of

giving results in accordance with the provisions of the specification. If the flux covering is of a

type requiring special protection during storage, the details and reference to this should be

included in the marking of bundle or box of electrodes, the electrodes shall be stored in a dry

store room."




24

6.1.4 Welding sequence:

6.1.4.1 To avoid distortion, weld metal shall be deposited following a proper sequence so as

to achieve uniform welding as well as low heat input. The runs shall be deposited in turn on the

right wing rail, nose and left rail as per RDSO/Lucknow. In case of switches, stock rail should be

reconditioned before the tongue rail.

Example for welding sequence:

In case skip welding is started from right wing rail, sequence will be in the order as under:

Set A-Right wing rail (RWR)-I, Nose-II and Left wing Rail (LWR)-III

Set B-RWR-I Nose-II, and LWR-III

Set C-RWR-I, Nose-II, and LWR-III and so on.

Similarly, if skip welding is started from left wing rail, the sequence will be as follows:

Set A-Left wing rail -III, Nose-II and Right wing Rail-I

Set B-LWR-III, Nose-II, and RWR-I

Set C-LWR-III, Nose-II, and RWR-I and so on.

A sample sequence of this process is as per RDSO/Lucknow.

6.1.4.2 A worn out tongue rail shall be reconditioned in the closed position i.e., resting against

the stock rail. Incase of a broken toe, however, the tongue rail is to be built-up initially and

hammer forged in the open position and there after the tongue rail shall be close with the stock

rail to attain the final profile.

6.1.5 Welding plant & Accessories:

6.1.5.1 DC or AC are welding plant shall be used. Instruments, cables and the accessories shall

conform to the requirements of the relevant Indian Standards wherever available. Their capacity

shall be adequate for the welding procedure laid down. All welding plants shall be maintained in

6.1.5.2 All electrical appliances required with the welding plant shall be properly

earthend.

6.1.5.3 Means for measuring the current (tong tester) shall be available in addition to the

current setting panel integrated with the welding plant as the actual output of welding current may

not be equal to the current as set on the control panel in many classes, especially when the plant

becomes old.

6.1.6 Pre-heating.

The points and crossings shall be pre-heated by oxy-acetylene flame to a temperature between

250 degree centigrade to 300 degree centigrade before welding. This temperature shall be

maintained throughout the welding operation. If welding is to be interrupted for some reason,

then the portions to be reclaimed subsequently shall be preheated again to the above temperature

range before welding is continued. The pre-heating and interpass temperature shall be measured

either by contact type pyrometer or tempil stick. No post heat-treatment is required after welding.

6.1.7 Current condition:

The current range as recommended by the manufacture for the particular brands of

electrode selected for welding shall be used.




25

6.1.8 Welding operation:

Welding shall be carried out in the flat position following the welding sequence as

mentioned in para 6.1.4.1. They are shall be struck on the points/crossing and then the

electrode shall be progressively advance by maintaining they are using uniform movement.

Care shall be taken to fill the crater to the full weld size before breaking they are to avoid

formation of crater cracks. During re-start of the welding operation, they are shall be struck

ahead of the crater and then drawn back. Slag shall be removed thoroughly in between runs.

Depending on the depth of wear, the number of layers to be deposited shall be assessed and

sufficient weld metal shall be deposited to provide as excess of weld metal by about 3mm

which finally be finished by grinding. An interpass temperature of 250 degree centigrade to

300 degree centigrade shall be maintained throughout during the welding operation.

6.1.9 Welding operation.

After completion of welding, reconditioned area shall be ground off in accordance with the

original contour of the rail. A straight edge along with a proper template may be used to check

the profile after finish grinding. During grinding, the grinding wheel shall be moved back and

for the over the area and not stopped at one stop to avoid high –localized heating and cooling,

which may result into formation of grinding cracks. The grinding wheel shall be kept properly

dressed to have a clean cutting surface, as a smoothened and loaded face will increase frictional

heat and proneness to grinding cracks.

7.0 MEDIUM MANGANESS STEEL OR 90 UTS POINTS & CROSSINGS (In Situ):

7.1.1 History of the crossing:

Before start of welding, the history of the crossing shall be collected and recorded on a card or

register. The details to be recorded shall be as indicated in para 7.1.9

7.1.2 Wear pattern.

The wear pattern shall be recorded along with depth of wear measured at ten different locations

marked as per RDSO/Lucknow.

7.1.3 Grinding.

The work hardened, fatigued and loose metal if any, shall be removed by minimum grinding.

Cracks if any shall be completely removed by grinding and then the surface shall be tested by

magnetic particles or by dye-penetrant test. In case, deep cracks are present, the same may be

removed first by special cutting electrode followed by grinding.

7.1.4 Electrodes.

Only RDSO approved H3 series of electrodes of double electrode system shall be used.

7.1.5 Pre-heating.

The tongue rail or nose and wing rails of MM/90 UTS steel be preheated on the surface by to

and fro play of oxy-acetylene torch so that a rail temperature of 250 degree centigrade (approx)

is maintained when depositing the weld metal. Once welding continues, blowpipe can be

withdrawn and the welding process will itself sustain the inter pass temperature of 250 degree

centigrade.

7.1.6 The crossing shall be welded following proper weld sequence for ensuring uniform and

minimum heat input. For this purpose, weld metal shall be deposited alternatively on left wing

rail nose and then right wing rail. Lower side of the recommended current range shall be used

with shortest possible arc. Weaving may be carried out but it should be minimum. Slag

inclusion shall be removed by suitable hardwire brush having three rows of bristles on 25mm

width and suitable hardened chipping hammer having pointed and flat ends. Incase DC-welding

is recommended polarity. After completion of welding, reclaimed area shall be carefully

checked for presence of sufficient metal at each point and presence of any weld defects.




26

Undercut, groove or any other defect, if noticed, shall be removed immediately by electrode

cutting followed by re-welding when the crossings still remain hot. Only 4.0mm dia electrode

shall be used and in rainy season, such electrode shall be preheated at 130-170 degree

centigrade for at least one hour immediately before use. Incase, the packing of electrodes is

absolutely intact and the entire electrode are consumed within 06 (six) hours after opening of

the packing, preheating of the electrodes may be dispensed with.

7.1.7 Welding generator.

Diesel/Petrol – driven portable welding generator shall be used for in-situ welding.

It should be capable of supplying 200 amperes at 6% duty cycles as mentioned in.

7.1.8 Passage of train.

Trains can be passed at normal speed over the weld-metal on crossing even before completion of

the hard facing operation. After passage of the train, welding can be started again. However, the

weld metal should be allowed to cool for a period of 2 to 3 minutes before allowing the passage

of train.

7.1.9 Records.

For each crossing, records shall be maintained at SE/PW‟s office showing station, point no.

up/down line, facing/trailing direction, traffic density, angles, UTS(72/90), date of last

resurfacing, traffic carried since then, date of present, resurfacing, wear readings, (depth in mm)

at locations as per RDSO/Lucknow on left wing rail, nose, right-wing rail, brand and size of

electrode used, quantity of electrode consumed (in Nos. or Kg) grinding time, welding time, total

time taken, no of trains passed during welding and name of welders. (Performa given as per

RDSO/Lucknow may be used for this purpose). These records shall be diligently maintained so

that these can be used to monitor/improve the productivity/quality of work of the welder.

7.2 Switch Expansion Joints:

The worn out tongue and stock rails of SEJ may be reconditioned by welding as per requirements

of field officials. It will be preferable to do reconditioning of SEJs in- situ to avoid de-stressing of

LWR panel. The process as recommended for reconditioning of MM steel 90/UTS points &

Crossings at para 6.1 or 7.0 above shall be followed.

7.3 Austenitic Manganese Steel Crossing (CMS Crossing)

7.3.1 Surface preparation.

The portions to be reclaimed shall be ground by pneumatic or electrical grinder to remove all

work hardened metal, spelled edges, cracks, adherent scales etc. it shall be ensured that before

Welding shall generally be done using 4.0 mm dia. Electrodes to avoid high heat input. The

electrodes having cracked and damaged flux covering shall be discarded. The electrodes shall be

stored in accordance with the directions laid down in IS: 814-1994 as explained in para 6.3




27

7.3.3 Welding sequence

Rectification of defects by welding of Austenitic Manganese Steel Crossings requires great care

in reducing the heat input. The cycle shall be short i.e., not more than two minutes at a time and

on no occasion more than one run shall be deposited. It is advisable to follow skip welding

sequence or to weld different portions of the crossings by rotation keeping the intervals adequate

to ensure that the temperature of the adjoining areas remain below 150 degree centigrade. The

runs may preferable be deposited in turn on the right wing rail, nose and left wing rail in case of

crossings following a skip sequence as explained in para 6.1.4.1.

7.3.4 Welding plant and accessories.

The welding plant, accessories and precautions, during their use shall be same as mentioned

in para 7.3.2 & 6.1.5. However, DC Generator with reversed polarity will be preferable.

7.3.5 Pre-heating.

Due to its low thermal conductivity and possibility of brittle structure formation, it is not

advisable to pre-heat the crossings before welding as done in case of medium manganese steel or

90 UTS points & Crossings. Interpass temperature shall always be maintained below 150 degree

centigrade by keeping adequate intervals in between the run and cooling the weld deposit and

heat affected zone by means of compressed air jet or water quenching immediately after welding.

Alternatively the crossings may be kept submerged in water bath (water tank made of either

masonry or steel plate wall) so that only top 1 cm of the crossing remains above the water level.

The interpass temperature shall be measured either by contact type pyrometer or tempil stick. No

post-heat treatment is required after welding.

7.3.6. Current Conditions.

Welding shall normally be carried out with the reversed polarity to minimize vibration and

heating of the coating or as recommended by the electrode manufacturers. Current on the lower

side of the recommended range and short are length shall be used to reduce the heat input in the

base metal, thereby reducing the dilution of the weld metal with the base metal, which would

otherwise cause embitterment in the weld.

7.3.7 Welding operation.

Welding shall be carried out in the flat position following the sequence as recommended in para

6.1.8 except that at no stage the temperature of crossing shall be allowed to go beyond 150 degree

centigrade. They are shall be struck on the crossing and then the electrode shall be progressively

advanced by maintaining they are with uniform movement. At a time, a run of about 7 to 8cm

length only shall be deposited by using weaving technique with the electrode held at 45 degree

angle to the direction of welding. The width of the bead shall be twice the diameter of the

electrodes and the arc length approximately equal to the electrode diameter. Care shall be taken to

fill the crater and then drawn back. Slag shall be removed thoroughly in between the runs.

Depending on the depth of wear, the number of layers to be deposited shall be assessed and

sufficient weld metal shall be deposited to provide an excess of the weld deposit of about 3.0mm

which shall finally be finished by grinding.

7.3.8 Grinding Operation

After completion of welding, the reconditioned areas shall be finished by grinding to obtain a

smooth surface. The sharp edges along the flange-way shall be ground to proper radius and

profile with the help of templates, so as to match with the original contour of the rail. A straight

edge along with a proper gauge may be used to check the profile after finish grinding. During

grinding, water shall be sprayed frequently and the grinding wheel shall be moved back and forth

over the whole area and not stopped at one spot so as to avoid high localized




28

heating and cooling which may form grinding cracks. The grinding wheel shall be kept properly

dressed to have a clean cutting surface, as a smoothened and loaded face will increase frictional

heat and proneness to grinding cracks.

7.3.9. Welding Site.

Austenitic Manganese steel contains high percentage of alloy elements (Manganese 11-14%

Carbon1-1.4%) and also has lower thermal conductivity. As such, it requires special welding

procedure and precautions for obtaining crack free weld deposit on them. The process needs

cooling of the weld deposit intermittently by water or compressed air to maintain the temperature

below 150 degree centigrade thereby requiring longer time for welding. In view of this, it will be

advisable to weld such crossings in a depot.

7.3.10. All points and crossings, switches and SEJs after reconditioning at inspection shall be

thoroughly cleaned of rust, scales etc. by brushing/mechanical cleaning and painted as given

below

1. One coat of ready mixed zinc chrome paint to IS 104-1988 followed by one coat of

ready mixed paint zinc chrome primer to IS 2074-1989 or two coats of ready mixed red oxide

zinc chrome primer to IS 2074-1989.

2. Finishing coat of ready mixed paint VERDIGIL GREEN TO ISC 280 to IS 117-

1998.

3. The thickness of the complete system of paint shall not be less than 80 microns (IRS

T-10 -2000)

7.3.11 All reconditioning component with crossing, switches and SEJs after final painting shall be

marked with contractors initials, agreement number, month and year of reconditioning by

stenciling in 50mm size with paint on the web portion of the switch/crossing SEJ.

7.4 Precautions in Metal Arc Welding

The welding arc is a point of intense heat, it emits harmful Ultraviolet and infrared rays and

fumes which may cause inconvenience to the welder. Hot metal, slag and spatter can often be

hazardous to the operators. Adequate precautions are, therefore, required to safeguard from:

(i) Electric shock

(ii) Radiation from the arc

(iii) Scattering hot particles and globules of metal and slag.

(iv) Flying pieces of sharp slag when being chipped.

(v) Heat and fumes.

8.0 Testing and Inspection

8.1 The resurfaced points and crossings after cooling and finish grinding shall be subjected to a

visual inspection, dimensional measurement and freedom from the presence of any surface

defects during welding i.e. under profile cut, slag inclusion, porosity, cracks etc. The finished

dimension after recondition should be as for new switch/ Crossing/SEJ.

8.2 The points and crossings found to be free from any defect during visual examination shall be

subjected to magnaflux or dye-penetrant test to ensure freedom from the presence of any surface

crack which may not be detected during visual examination. The details of the magnaflux and

dye-penetrate tests.

8.3 Rectification of defects after testing and inspection.

During visual inspection and magnaflux and/or dye-penetrant tests, cracks or other weld defects

are found, the portion containing the defects shall be gauged either by pneumatic gauging or

grinding and the remaining portion shall be re-examined by dye-penetrant tests for ascertaining

free from any crack or detect before under taking further repair. In the absence of any crack. The

portion shall be re-welded, ground and inspected by following the recommendations as

mentioned above.




29

8.4 Periodical Inspection.

After laying in track, the resurfaced points & crossing shall be inspected quarterly in order to

record the amount of wear on the nose, left wing and right wing rail as well as stock and tongue

rail and also for the structural soundness, presence of dis-integration or only other defects. Wear

shall be recorded in crossing at ten different locations marked (A1, A3, B1, B3, C1, C2, C3, D1,

D2 & D3) as per RDSO/Lucknow and in tongue rails at seven different locations starting from

one at toe to places each 100m away towards heel side and up to 600mm from the toe.

9.0 Recoveries

If the reconditioned switch/crossing/SEJ fails after laying in the track before achieving the

prescribed minimum GMT for the class of electrode used the recovery shall be made at twice the

accepted rate from the security deposit/ guarantee money lodged with railway.

9.1 The welding electrode of 4mm dia having valid and current approval as prescribed by RDSO

under H3 series shall be arranged by the contractor. The contractor will have to produce

documentary proof of having procured the approved brand of electrode from authorized stockists

duly supported by necessary test certificate issued by the manufacturer of the electrode.

The approved list of manufacturers issued by RDSO is subject to revision every year. The

contractor shall procure welding electrode from the current list approved by the RDSO for

manufacturing of these electrodes.

9.2 Responsibility of obtaining of materials, plants, machineries required for the performance

of the contractor shall entirely rests with the contractor.

10.0 The rate of reconditioning work shall be inclusive of cost of labour, materials,

consumables, tools and plants for finishing and machinery etc. including reassembling of the

crossing in case of built up crossings complete for the above. The accepted rate is deemed to

include cost of all incidental works including lead and lift.

layer).

2. Welding Power Source:

2.1 A standard D.C. set with 80 OCV or standard A.C. set with 90 OCV.

3. Preparation of work:

3.1 Work-hardened, deformed, spalled, chipped & cracked material must be removed

from the old crossing by mechanical grinding, till sound & bright rail material is exposed. No

rust is permitted on areas to be welded.

3.2 Ensure grinding operation with light pressure, to avoid localized overheating.

3.3 Only mechanical grinding is to be used for material removal. Flame or arc gouging

must not be used under any circumstances.

3.3 Standard Dye Penetrant Test to be carried out prior to welding, to confirm absence of

structural defects in the rail material. Thereafter, thoroughly clean all surfaces to be

welded, by using a residue-less solvent (such as Acetone).

4. Steps for repair:

4.1.1 Built-up Crossings:

Pre-heat the areas to be repaired+3 inches on either side to approx. 100 degree

Centigrade. Check the temperature with indicating crayons. Use fresh electrodes(less than 1 year

old) from sealed dripack. Remove only consumption quantity of electrodes at a time from the

dripack. Dripack should be promptly closed thereafter. Electrodes are to be used for welding

only after drying at 150 degree Centigrade for 60 minutes.

4.1.2 CMS Crossing:

NO PREHEATING TO BE DONE:

CMS crossing to be immersed on running water. Only 2 -3 mm portion where

welding has to be done should be projected out of water. Interpass temperature is to be

maintained around 100 degree centigrade.

4.2 The built up is carried out in 2 stages. First layer (buffer layer) is to be deposited

using CP BUFFER 040 – 3.15 mm. Subsequently, 3 layers (hard-surfacing layers) are to be

deposited, using CP TOP 080 – 4mm. The total built up (buffer + top) will be approx. 10-12mm

5. Deposition of buffer layer with CP Buffer 040:

5.1 Using D.C (electrode positive) or A.C. power source & suitable current setting (100-

130 Amps at electrode holder during welding), deposit stringer beads with short arc length. Use

of calibrated portable A.C. /D.C. Tong Tester is recommended to ensure correct electrical

parameters. Maintain interpass temperature 100-150 degree centigrade throughout the welding.

Each deposited bead should be thoroughly de-slagged & wire brushed, prior to deposition of next

bead.

in 100ml., of concentrated Hydrochloric Acid (specific gravity 1.16).

5.1.1.3: Immediately before tests, prepare the stripping solution by adding 5ml. Of the solution prepared under

5.1.1.2 to 100ml. Of concentrated Hydrochloric Acid (Specific gravity 1.16). Mix well.

5.1.1.4: Procedure: (I.S:6745-1972): weight and cleaned test specimen whose mass is less than 200g. Nearest to

0.01g for test pieces whose mass is between 300 to 1000g. Weight to the nearest 0.1g and for masses over

1000g., the accuracy of weighing Shall be nearest to 0.5g after weighing immerse each test piece singly

in test solution prepared in 5.1.1.2 and allow to remain there until the violent evolution of Hydrogen ceases

and only a few bubbles are being evolved. This requires about I5 to 30 secs.

5.1.1.5: The mass of Zinc coating of g/m sq. of surface may be calculated as per the following formula: -

M = M1 – M2 x t x 3930

M2

Where M= Mass of Zinc locating in g/m sq. of surface.

M1 = Original Mass in gm., of test piece

M2 = Mass in gm of stripped test piece, and

t = thickness of the stripped test piece in mm.

5.1.2.: Magnetic or microscopic method as per IS: 3203-1965 ireddy current method ;as per IS:6012-1970 may be

employed to determine the thickness of coating. The mass of coating in g/m sq. Shall then be calculated

by multiplying the thickness in mm. by a factor 7047.

5.2: Determination of Uniformity of galvanised coating: where practicable the uniformity of galvanised coating

shall be determined by the Preece test as prescribed in IS.2633-1972. The article should withstand four 1-

minute dips.

in IS:2629-1966.




57

6.0: INSPECTION:

6.1; Visual inspection of material shall be made to determine conformity with the requirement of 3.2 when

partial inspection warrants rejection of a lot, the Galvaniser may reject the lot and submit it once again for

inspection.

6.2: Should one specimen/specimens fail to conform to the requirements specified in 5 for the mass of coating

the second and third specimen/specimens shall be tested. Failure of either the second or third

specimen/specimens to conform to the requirement shall be the cause for rejection of the lot which the

samples represent.

6.3: Materials that have been rejected may be stripped and re-galvanised and re-submitted for inspection and

test when they shall conform to the requirements of this specification, otherwise the entire lot shall be

rejected.

7.0: RECTIFICATION OF DAMAGE:

7.1; Normally all fabrication work in the case of galvanised articles shall be completed prior to galvanising. If

for any reason, fabrication such as cutting, drilling or welding has to be under taken after galvanising,

protection of metal exposed as a result of fabrication and rectification of damaged galvanised areas shall be

done in accordance with either of the following methods or any other method approved by the Railway

Administration.

i).Sticks or rods, 5-10 dia of high purity Zinc shall be used for this purpose. The surface to be protected,

or the surface where galvanising has bee damaged , shall be cleaned and any oxides removed with a weak

acid solution and a wire brush. The surface shall be thoroughly washed with water to market it free from

any traces of acid. The cleaned area may be heated with welding torch and rubbed with white

salammonic. A piece of the stick or rod high purity shall be melted on those areas and spread out with a

heated piece of salammoniac. The area shall then be washed down by water and lightly wire brushed. The

workmen ship shall be such that the finished surface is smooth and non/porous.

ii.)The damaged surface after cleaning, as mentioned in para (1) above, shall be painted with two or more

coats of Zinc rich primer followed by a finished coat, as per the painting Schedule recommended by the

supplier or Zinc rich primer.

iii)It is to be ensured that the dry film thickness of Zinc rich primer shall not be less than the average

thickness of the galvanised coating. The complete painting system i.e., Zinc rich primer

with the finishing paint for this purpose shall be procured from the same source of repute and as approved

by the Railway Administration.
