relaxation of base metal in accordance QW-423.1 ASME IX Welder qualification
(OP)
hey guys, i think that following my query already available in this Section but it could be not found out, so i do a repeat is can i use P.1 base metal to be qualified a welder with purpose for welding production of P.8, the WPS used for this welder qualification is P.8 WPS. that is why i asked you guys this question because long time ago my client they allowed doing like this.
Actually, i have doubt to, refer QW-301.2, it is mandated a approved WPS presents at the time of welder qualification.

Of course F# is an essential variable.

More specifically, please see below to be clarified:
#1: Refer to QW-301.2, it means that during welder qualification, we needed to present a WPS hence the base metal for this welder qualification shall be complied with presented WPS. it mean we can not qualify welder with carbon steel coupon with approved stainless steel WPS.
#2: Refer to QW-423.1, we can qualify welder with CS coupon with present of approved CS WPS and then the qualified range of this welder could be covered for SS welding production.
also everybody please help me to confirm the point of #1 & 2#.

#1 is not correct. QW-423.1 tells you that it is acceptable to substitute the base metal in the WPS for an alternate base metal. You can qualify a welder on a carbon steel coupon even though the WPS is for stainless....and vice versa.
#2 is correct, assuming F# is the same. Qualification on P1 qualifies for P1 thru P15F, P34, and P41 thru P49.

SFA 5.4 is the specification for "stainless steel electrodes for shielded metal arc welding". It is a broad specification and therefore it contains many different F#s.
For example: SFA 5.1 contains - 7024 (F#1), 6010 (F#3), 7018 (F#4), all carbon steel electrodes for shielded metal arc welding.
