This topic seems quite interesting and I see divided opinions, I allow myself to give my opinion and if it is incorrect I hope that someone with more experience will give us more light and knowledge on this important topic.
Attached image of a part of a Welder Qualification, this was used for an ASME Audit, in other words it was reviewed by the ASME Authorized Inspector; two points:
1.- ASME IX works very differently than D1.1 does.
2.- In the column with red box: Range Qualified cross with Metal Base, there is a list of Numbers P (1 THROUGH 15F; 34 AND 41 THROUGH 49), I understand that the welder in this case was qualified for P1 with P1 but that has the ability and qualification to weld all P1 THROUGH P15F steels; P34 AND P41 THROUGH P49 and the combinations between these materials. It should be mentioned that this is suggested to the F-number, qualified position, thicknesses and diameters. in fact in an API course I heard that under ASME IX only three coupons are needed to qualify a welder in all materials, this if you do not take into account: F number, position, thicknesses and diameters. I will thank you infinitely for your contributions.
--Greetings George,It would be intresting if we know why it is not possible for this below case? with references, so that we can learn / adopt, your point of view, if it is acceptable.Thanks.
