Re: Re: [MW:29994] WPS

Hi,

Your process is SMAW, which is QW-253, G no is Supplymentry essential variables and it becomes essential as per QW-403. (b) and (c) second paragraph clause.

If G1 vs G1, you cannot use as per above as A 105 is G2, where as still if your A 106 falls under grade C again this also falls under G2 (If A or B then G1) however A 105 is G2, hence irrelavant of impact or non impact G1 vs G2 combinations not ensured in WPS, so as per your approved WPS and as per above clauses, strictly you cannot use this current WPS for propsed material.

Thanks,

Dear,

Please note that P number is same (P1 to P1). For group number A106 Gr. B Gr.1 and for A105 Gr. 2 ( Group Number only applicable for impact test requirements) so if there is no impact requirement you can use.
