STANDARD REBAKING PROCEDURE FOR LOW HYDROGEN ELECTRODES

0i) Rebake the electrodes at 250-300 C for one hour.0ii) Cool them in the same oven to 100 C.

0iii) Transfer them to a holding oven maintained at 60-70 C.

iv) Draw from this oven for use.

v) Do not keep rutile type electrodes in the same oven.

REPAIR WELDING OF CAST IRONS

- Grind the area to be welded so that the casting skin is removed.

- Clean the area free of all contaminates by degreasing, burning, brushing, grinding, etc.

- If a crack has to be repaired drill crack arrester holes at the end of the cracks. Remove the crack completely by gouging, grinding, etc. and ensure complete removal by a dye penetrant test.

- Deposit the welds in small lengths of 50 mm at a time.

- Peen the welds.

- After welding allow the casting to cool slowly.

- These are the general steps in cast iron welding. However, the procedures may have to be modified depending on the job. For complete welding procedure details contact our technical service personnel.

CAUSES AND REMEDIES FOR FUSION WELD DISCONTINUITIES

CAUSES CORRECTIVE ACTION

A. POROSITY1. Contamination of work piece - Clean joint area2. Excessive moisture pickup in - Store electrodes properly

electrode covering - Follow manufactures recommended rebaking procedure

3. Moisture on work surfaces - Use preheating/warm up work piece.4. High Sulphur content - Use basic coated base metal electrodes5. a) Long arc length - Change welding parameters and

b) Excessive current techniquec) Higher travel speed

6. High solidification rate - Use preheat- Increase heat input

B INCLUSIONS1. Improper cleaning procedure - Clean work surfaces and each weld run

thoroughly. Wherever necessary use power wire brush, grinders, chisels to ensure a thorough removal of slag

2. Improper welding techniquea) Excessive weaving - Improve welding techniqueb) High travel speed - Reposition work to prevent loss of

slag control wherever possiblec) Slag flooding ahead of - Restrict weaving to a minimum welding arc

3. Narrow, inaccessible joints - Increase groove angle

CAUSES AND REMEDIES FOR FUSION WELD DISCONTINUTIES


C INCOMPLETE FUSION

1. Improper joint design - Increase included angle of groove joint

- Change the groove design

to a 'J' or

a 'U' type

2. Presence of slag or oxide film - Clean weld surfaces prior to welding

3. Incorrect electrode position - Maintain proper electrode position and

and operating current current

4. Improper manipulation of arc - Use correct manipulation techniques to

melt the joint faces properly

D INADEQUATE PENETRATION

1. Improper joint preparation

a) Excessively thick root face Use proper joint geometry

b) Insufficient root opening Reduce root face height

c) Bridging of root opening Use wider root opening

2. Electrode diameter too large - Use smaller electrode in root

- Increase root opening

3. Inadequate current - Follow correct welding current and

technique

CAUSES AND REMEDIES FOR FUSION WELD DISCONTIUTIES


E. CRACKS

1. High rigidity of joint - Use preheating

- Relieve residual stresses

- Minimise shrinkage stresses, using back step

or block welding sequences

2. Poor joint fit up - Adjust root opening all alignment

3. higher carbon content of weld - Use proper electrode

metal and/or hardenable - Use buttering layers wherever necessary

base material

4. Too small a weld bead - Decrease travel speed to increase

cross section of bead

- Increase electrode size

5. High sulphur content in base - Use filler with high level of sulphur fixing

or weld metal element like Mn

6. Hot cracking - Reduce the heat input.

- Minimum joint restraints

7. Cracking at the crater - Filling up the crater before withdrawing

the electrode

- use taper power control device

- use back step welding technique

8. Higher hardenability - preheat the job

- Post weld heat treatment without

cooling to room temperature

CAUSES AND REMEDIES FOR FUSION WELD DISCONTINUTIES


9. Hydrogen Induced - Use low hydrogen welding electrode

cracking/Delayed cracking - Use suitable preheat and post weld

heat treatment.

10. Presence of brittle phases in the - Soften the material before welding

micro structure of the

base material

11. Low ductility of the base material - Use preheat

- Anneal the base metal

- Use ductile weld metal

12. High residual stresses - Redesign the weld metal and reduce

restraints.

- Change welding sequence

- Use intermediate stress- relief heat

treatment

13. Excessive dilution - Change welding current

- Use buttering technique wherever

possible
