If I have a 6G welder qualified to weld using ER70S-G for carbon steel, can he/she perform FILLETwelding on stainless steel plate using ER308L without requalification based on ASME IX?
Only if the F no for the SS wire is the same as the F no for the ER 70S. The Pno 1 BM qualification will cover the P no 8 for the 308 BM but that may not necessarily be true for the filler metal.
that's what I thought, but its common here to ask for new qualification cert whenever you're transferred from c/s to s/s welding. I agree that you need to produce a new cert if your are ask to weld s/s butt joint that needs backing gas.
Addition of purging does not require requalification. Only the deletion of it when it was performed on the qual. Plain ole carbon to carbon with carbon will get you "legal". That may not mean I person can slick one on a piece of schedule 10.
you mean to say that no need a requalification test prior to welding of stainless steel-root pass if you have already been qualified to weld in carbon steel-root pass?
(for GTAW) The Company may have a requirement that you qualify with s/s to weld s/s... but the ASME Code does not require a new certification test. If you qualify with an F6 electrode, you are qualified to weld with any F6 electrode.
thanks Bill M, it will surely help my boss to save his money by avoiding the requalification of our welders. I will tell my boss, he may reward me for this good news as Christmas is coming soon.
