How old a WPQ to Accept?
(OP)
I have a contractor submitting WPQ for his welders dated 1994,'97,'98,and '99. Spec is b31.3 gmaw for astm a53 pipe line work. I think this is to old a WPQ and I should request new. Any industry guidelines, Thanks

One other thing is though the code itself is silent, some client specifications specify that only joints with some NDE can be used for maintaining continuity, hence if a fillet weld/ bridge tack data presented for extending continuity, it would not be acceptable as per those specs.

as per asme section ix. check his welding( welding process) continuity log, within six month period, if he has not welded with a process which he has qualified already , then requalification is required
