Essential variable - ASME SEC IX

Essential variable - ASME SEC IX

Essential variable - ASME SEC IX

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.

RE: Essential variable - ASME SEC IX

You don't say what process you're using, and there are differences in base metal variables based on that. Regardless, I don't see that the base metal heat treatment is an essential or supplemental variable.

RE: Essential variable - ASME SEC IX

You won't find it in Sec IX. It will be in the construction code, much like UG-84(h)(2). Not sure of the requirements of B31.3.

RE: Essential variable - ASME SEC IX

Can you list the materials - may be easier to assist.
