RE: [MW:27111] Qualifications of welders

To All Concerned,

 

A new qualification is required in this case. Qualification on other austenitic stainless steels(P No 8) does not permit the validity of qualification for duplex stainless steels (P No 10H). It's clearly stated under QW-353, please see the extract below.

 

F No for both ASS and DSS are the same, F5 for SMAW (SFA 5.5) and F6 for GTAW/GMAW(SFA 5.9).

 

Thanks.
