QW-403.6 is applicable for minimum base metal limits for impact tested qualification, What i m asking is that, QW-451.4 is stating that a groove weld qualification shall be qualified for all thickness of fillet weld, does that mean, we need not to follow QW-451.1 & QW-403.6....
Somebody please answer this query......
