Hello, i have a question about QW 404.12 in case of GTAW process with impact test requeriment (-196ºC).
If a filler metal classification (ER 316 to ER 308) is change in the same SFA specification (Both filler material are A5.9), i must requalified a PQR.
But, there is several exeption (maybe 404.12 e and f) that maybe allow me to change filler metal from ER316 to ER308 without new qualification.
Thanks
