STOP START

Because :
  • Bulge recurring caused by replacement electrodes too backward so there overlapping prominent.
  • The empty without capping in a recurrent manner caused by the replacement of electrodes too forward.

Result
1. THE STANDOUT LOOKS BAD AND INEFFICIENT
2. That empty inflict NOTCH Potentially crack.

Countermeasures :
1. Prominent grinding sufficient in to the standard
2. Thr empty grinding must be to rest of slag missing , then welds rearranged wps repair

Rejection criteria :
1 .To prominent recurring acceptable on the condition in burrs to the form of standard.
2 .To empty acceptable origin repaired by filling capping to the form of a welds uniform .If this mentioned above not carried out , the welds rejected

Because
1. Metal temperatures too low.
2. Ampère capping too low.
3. Dirty.
4. Swing not fix.
5. HIGH LOW.

Result
1. arise NOTCH Potentially crack.
2. Weaken connection weld.
3. Started rust the surface.

Countermeasures :
Grinding until defect missing, Welds repeated according WPS repair.

Rejection criteria :
If defect weld not repaired , the welds is rejected.
