Assume your question is based on ASME BPVC Section-IX and the PQR was not impact tested.

You can prepare two WPS from a combination welding process PQR based on ASME BPVC Section-IX, QW-200.4 (a)


Given Data - Actual PQR Details


Base Metal Thickness = 12.7 mm Thickness = 9mm GTAW SMAW Thickness = 3.7mm





Two qualified for Range as per QW 451.1 WPS WPS GTAW Qualified Base Metal Thickness Range = 5 mm to 25.4 mm Thickness Qualified Range = 18mm GTAW SMAW WPS Qualified Base Metal Thickness Range = 5 mm to 25.4 mm SMAW Qualified Range = 7.4 mm Thickness
