I want to make absolutely sure about this..., I have a WPS that is P1 to P1, per QW-424, the qualified base metals for that procedure is metals contained in p1 only. Now for Welder qualification, the welder testing to the WPS above, can use p1-15F, 34,41-49 for testing but is only qualified the same as the WPS he is testing too... p1 to P1? This is not what pro write is kicking into the qualification range for the welder, it is listing the whole range above. Am I missing something here? I see this under alternate base materials for welder qualification". Not all materials a welder is qualified to!
