Dear Experts,--
We prepared one PQR alloy steel grade P91 welded to carbon steel.Coupon test welded GTAW/SMAW ER90SB-9 / E9015-B9. Our client reject the PQR and said that the filler metal shall be compatible with the lower grade (with crabon steel) in our case.
Do we have any support from code/standard and any metallurgical impact.
Construction code : ASME B31.1
