Re: [MW:23276] Multiple WPS from single PQR

Thank You For reply

My humble doubt is, 1 ) weld metal deposition is restricted to be max 6 mm for gtaw, and 13 mm for SMAW, what is the advantage of having 19 mm as  Qualified base metal thickness. For separate process there is no advantage of Base metal Qualified as per QW-451 ie 1.5 to 2T

AM I RIGHT ???

Backing is a welders qualification essential variable. For PQR it is a nonessential one.

The Base metal qualification range is the same for the 3 cases

But for SMAW single process you have to give Metal baking as the GTAW weld Metal act as metal baking.
