[MW:19126] Re: Change in Supplementary Essential Need re-qualification?

Dear All,

Please be informed that we have carried out the WPS & PQR of P No-01 Group no.01 materials with notch toughness test (including HAZ).

With reference to above, Can I establish a WPS of P No-01 Group no.02 materials as per ASME Section IX latest edition???

Your prompt & valuable respond along with details will be highly appreciated.

Thanks & regards,

Dear Experts,

i need your clarify that the changes in material group number with the
same p number need another welding qualification or not.

my case i have WPS for A312  grade TP 316, P no. 8 , group no. 1 to itself.
it's right to use it to weld  A312  grade TP 310s, P no. 8 , group no.
2 to itself.
