QW-200.4 of ASME Sec. IX_Combination of Welding Procedures

[sushildwivedi16]

Hello Everyone,

This is my first post here. Hope to find the solution to my query with respect to QW-200.4 of ASME Sec. IX.

Here I go!!

PQR A is qualified in 25 mm base metal thickness with 10 mm of GTAW & 15 mm of SMAW weld deposits. PQR B is qualified in 8 mm base metal thickness with 3 mm of GTAW & 5 mm of SMAW weld deposits. In both the PQRs, the tensile and bend tests have been carried out satisfactorily.

Can I generate a single WPS of GTAW process only with base metal thickness range as 1.5-50 mm, GTAW weld deposit max thickness - 20 mm ?

The production joint thicknesses are 4.55 mm and 12 mm and do not require impact testing and have to be welded entirely with GTAW process only.

Also can I generate a second WPS of GTAW+SMAW process with base metal thickness range as 1.5-50 mm, GTAW weld deposit max thickness - 20 mm, SMAW process weld deposit max thickness - 30 mm ?

Thanks to all in advance.
