COMMON PROBLEMS AND REMEDIES
Possible Reasons
Possible Remedies
1. High rigidity of joint
1. Preheat, use peening, change welding
    sequence, increase cross section or bead
2. Unsound welds
2. Check for porosity and inclusions.
3. Defective electrodes
    (high or low moisture in coating,
    poor core wire)
3.Change electrode, control moisture by
    proper storage.
4. Poor fit up.
4. Improve edge preparation and fit up
    Reduce root gap.
5. Small or shallow bead.
5. Increase cross selection of bead.
    Change electrode type/size.
6. Excessive carbon or alloy pick up
     from base metal.
6. Reduce penetration by low current and
     increase travel speed. Change to low
     penetration electrode.
7. Angular distortion, causing tension
    at root run.
7. Balance welding on both sides, use peening.
8. Excessive sulphur in base metal.
8. Use EXX 16 electrodes.
