First posting.
I need some opinions on the interpretation.
Per AWS D1.1:2004 Table 4.6 item #1 states "A change in group number" SMAW, SAW, GMAW, FCAW, & GTAW.
As I understand it, if a procedure is qualified with impacts per contract / specification requirements and the base material qualified was for example group II to group II. Then only group II is qualified. Any other combination is not qualified.
Here is what I am not sure of since I get multiple opinions. If a procedure is qualified by welding group I to group II, and CVN's were tested in the following locations for group I side, weld, fusion line, fusion line + 2 mm,& fusion line + 5 mm. Then for the group II side, fusion line, fusion line +2 mm, and fusion line + 5 mm. Then are the following combinations also qualified per code along with group I to group II:
(1) Group I to Group I
(2) Group II to Group II
I say yes they are, but the third party inspector thinks otherwise, please help! I do not care if I am correct or not. I just want to know the correct answer. Thanks for your time.
