Change of Filler Wire

Change of Filler Wire

Change of Filler Wire

(OP)
Please kindly advise me whether a requalification of PQR is required when changing from ER-70S2 TO ER-70S6.
Since I have a WPS qualified with ER-70S2+E7018. However, due to the non-availability of ER-70S2 can I use ER-70S6 without qualifying for new PQR.

RE: Change of Filler Wire

Only if you can confirm the ER70S6 meets the A1 analysis, which you should be able to confirm easily.

RE: Change of Filler Wire

It would be helpful if you cited a specific code.

Best regards - Al

RE: Change of Filler Wire

My comment refers only to ASME IX, of course.

RE: Change of Filler Wire

Generally, when working to the Farm Code, electrode classification is not an essential variable. As long as it sticks until it breaks, all is good.

As I asked before, what is the governing code and I'll add the question; is CVN a concern?

Best regards - Al
