[MW:24761] PERFORMANCE QUALIFICATION



Dear Sir,

(B31.1 Code) We have a qualified pipe welder with 6G position (18.26 thickness test coupon), as per ASME Sec IX Table QW-461.9, he is qualified for all positions for groove and fillet weld - plate and pipe.
This qualified welder was task to weld pipe support (H Beam), It has been questioned by the TPI that this welder should be qualified again as per AWS D1.1.
My Questions are;
1. Should we qualify this welder again as per AWS D1.1? If yes, what is the supporting code for this.
2. Does ASME Sec IX Rules for this situation?

Need your advise.....


Thank you

Mac Palola
