Re: [MW:15306] Use of Group No. 2 Qualified WPS on Group 1 & 2?

Considering the Impact requirement , If you have a Qualified WPS for each P # Group # welded to itself  , then yes you can weld P1G1 to P1 G2 as per QW-403.5.

" two or more qualification records have the same essential and supplementary essential variables, except that the base metals

are assigned to different Group Numbers within the same P-Number, then the combination of base metals is also qualified"

Dear Expert,

For Vessel (ASME Sec. VIII Div. 1), 
Shell Material = SA 516 Gr. 70N (P. 1 G. 2) Impact Test required per code
Nozzle Pipe Material = SA 333 Gr. 6 (P. 1 G. 1) Impact Test is not Required per code

Can we use a WPS qualified with P.1 G.2 only to weld Nozzle to Shell joint in above mentioned Vessel.

Thanks
