Thanks...
RE: Welder Qualification
The short answer is that per ASME Section IX (the code, as well as me, lol) a welder qualified on 'carbon steel' (P1) is also qualified for P-No. 1 through P-No. 15F,P-No. 34, and P-No. 41 through P-No. 49 (stainless steels include P8).
Having said this:
The welder is restricted by QW 451.1 as well as other process limitations, as stanweld has indicated.

There are a few if's and wherefores that have to be checked first. Remember what the letters in ASME stand for: Always, Sometimes, Maybe, or Except.
Best regards - Al
