Essential variable - ASME SEC IX
Essential variable - ASME SEC IX
(OP)
Dear All,
I have 2 materials. One with normalized and other Normalized and tempered.
I have qualified a PQR -1 as per ASME SEC IX with impact requirements as per ASME B31.3 with base material normalized .
My job is having impact requirementsas per ASME B31.3 with normalized and tempered base material.
All the variables remains similar except heat treatment.
Can i use the PQR-1 for writing WPS to weld normalized and tempered base material?

RE: Essential variable - ASME SEC IX
As far as I know, heat treatment on base metal will not change the Base material P number and Group number. Therefore, the same WPS can be used since all essential and supplementary essential variables remain the same. Base material heat treatment is not a part of WPS. Therefore, there is no need to change the WPS.
