[For filler metal] Same AWS classification but different manufacturers.

[For filler metal] Same AWS classification but different manufacturers.

[For filler metal] Same AWS classification but different manufacturers.

(OP)
Dear Sirs.

Good day.

Please kindly refer to below my questions.

1. Now i have a Qualified WPS but it's designated only type(E8016-C1) and Manufacturer(Kobelco).
2. But as missed order from company that arrived diff manufacturer(Chosun) welding rods(but same AWS classification : E8016-C1)

So do i have to PQR again? Is it essential variable? or Non-essential variable situation?
Please kindly guide us for this matters.

Thanks in adv.

koodaehan,
If you are talking ASME IX then no problem at all with what you propose,

RE: [For filler metal] Same AWS classification but different manufacturers.

As DekDee said, for Section IX it is not a problem. If you are working to some of the EN welding specifications you may want to look very carefully at them since they often require a new PQR with change of manufacturer. They do make exceptions for solid rod but I don't recall the exceptions carrying over to the SMAW process.

RE: [For filler metal] Same AWS classification but different manufacturers.

Note that ASME does not discriminate as per Mfr or
Country of origin

RE: [For filler metal] Same AWS classification but different manufacturers.

It depends; if the WPS specifies a specific manufacturer or a specific trade name, the WPS must be revised as a minimum.

Best regards - Al
