[MW:34252] RE: 34251] Re: PQR WITH TWO WELDING PROCESS TO SEPERATE IT

Yes its possible, You can go for only SMAW considering all other essential variable

 

QW-200.2(f) One WPS. Several WPSs may be prepared from the data on a single PQR (e.g., a 1G plate PQR may support WPSs for the F, V, H, and O positions on plate or pipe within all other essential variables). A single WPS may cover several sets of essential variable ranges as long as a supporting PQR exists for each essential and, when required, supplementary essential variable [e.g., a single WPS may cover a thickness range from 1/16 in. (1.5 mm) through 11/4 in. (32 mm) if PQRs exist for both the 1/16 in. (1.5 mm) through 3/16 in. (5 mm) and 3/16 in. (5 mm) through 11/4 in. (32 mm) thickness ranges].

Hi there,

 

May you check in which standard refers to.

I understood, ASME IX allowed for thickness of test coupon more than 13 mm.

 

Thanks
