ASME Procedure Qualification Variables-Does Multi run cover single pass
(OP)
Hi Guys,
Procedure Qualification Variable Query
Does a multirun autogenous butt weld GTAW in PNo 43 material qualified to ASME IX cover you for a single pass autogenous weld in the same material,joint,process etc?(No PWHT)
I know EN 15614 Part 1 does not.
Thanks in advance

RE: ASME Procedure Qualification Variables-Does Multi run cover single pass
PQR: see QW-256. If you're talking orbital welding, yes, unless as per QW-410.9 notch toughness is a supplementary variable. If you're talking hand GTA welding with no filler; yes
WPQ - If you're talking orbital welding, as per QW-256; yes.
WPQ - hand GTA weldign with no filler as per QW-356; yes
