Dear All,
Good Morning !!!
I have a query on ASME SEC-IX ( 2007 ED, 08 ADD )
QW-403.5 (c ) , states that " --------------- In addition, when base metals of two different P-Number Group Number combinations are qualified using a single test coupon, that coupon qualifies the welding of those two P-Number Group Numbers to themselves as well as to each other using the variables qualified."
Query: If we qualify one PQR, with P-No. 1 Gr. No 2 to P-No.8 Gr.No.1 material using SMAW ( E 309MoL) process with impact testing on weld metal & both HAZ portion , does this PQR supports the following WPS combination of base metals , if all other welding variables are unchanged ?
(i) P-No. 1 Gr.No.2 to P-No. 1 Gr.No.2
(ii) P-No. 1 Gr.No.2 to P-No. 8 Gr.No.1
(iii) P-No. 8 Gr.No.1 to P-No. 8 Gr.No.1
Please give your comments,
Thanking you,
Regards,
