ASME IX PQR
ASME IX PQR
(OP)
Hi All
Regarding ASME IX is it possible to split a multi process PQR, i.e GTAW (Root & Hot Pass) & SMAW (Cap & Fill)? Thus enabling the GTAW process to be used seperattly from the SMAW?
Thanks in advance

I do not think the backing would be an issue as it is not an essential variable for Procedure Qualification of SMAW. It would however be an essential variable for the Welder Performance Qualification and should be concidered when writing the WPS and qualifying the welders. I may be wrong on this as I am working from memory and if I am please feel free to correct me.
