I am currently reviewing a P15E ASME Sec IX Weld Procedure. Need to know if you can weld out a 38mm thick SA-387-Gr-91-Cl-2 PQR test coupon using GTAW for the first 10 mm & then complete the test using GMAW. Then record only the 10mm GTAW Process on the WPS with GTAW only. Seems a little strange to me. Look forward to the great responses.
