Re: [MW:24971] IMPACT TEST REQUIREMENT

Mohammed: interpretation IX-92-70 does not address this situation

Balaji : You can use this PQR for welding P1 G1 to P1 G2, P1 G2 to P1 G2 and P1 G1 to P1 G1

PQR on P1Gr1 to P1Gr2 qualifies welding P1Gr1 to P1Gr2 only and NOT welding to themselves i.e ( P1Gr.1 To P1Gr1 Or P1Gr2 to P1Gr2)

Refer ASME interpretation IX-92-70 on the same subject.I could not find downlodable copy.Try to search on internet.

Thanks

Dear All,

As per ASME SEC-IX   change in material Group is Supplementry  essential variable (403.5)

based on above i need your experience  If iam qualified PQR p1 group-1 to p1 group-2 tow different group welded it self so the  qualfied range will be p1 group1 and p1 group 2.

or only this PQR is qualified group 1 to group-2 qualified.
