In this case... joint repaired twice and cut for hydrotest and re welded as Golden joint.
while cutting & re beveling the HAZ have been removed, hence its fresh joint ( golden weld) and repaired only once.
basically while repairing due to sudden cooling the hardness in the HAZ will be increased which may leads to cracking...
