Yes

All mentioned joints you can weld with the same WPS if we don’t change any essential & sup-Essential variables.

No,

It applies to different group number within same P number, and not with different P numbers.

Any way why you are impact testing this combination (P1 # P8), what are your design conditions?

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,
