ASME Code Section IX
Paragraph QW-350, QW-356
Essential variable QW-403.18
We have a qualified welding procedure (WPS-A) to weld pipe, 6G, GTAW, P8 to P8
Is it permited by the BPV IX to qualify a welder substituting the base metal of a qualified WPS-A in accordance with QW-423; in our case, changing the base metal from P8 to P1 for welder qualification?
is the welder qualified for WPS-A?
In other words, we have a qualified WPS-A, I want to qualify a welder according to that WPS-A, however I want to change the base metal (P8 for P1) as permitted in QW-423. Is this my interpretation correct?
Do somebody know the intent of ASME Sec. IX paragraph QW-423?
