WPS for butter pad - test specimen question

[timsch]

I've created WPS's for butt joints where there is a buttering layer. ASME BPVC SEC IX, QW-283 seems to be written with this orientation in mind; at least when I read -283.2.

I now have a job where I need to put a 4" x 6" x 3/16" alloy 625 butter pad on the OD of a P5 pipe to then weld temperature sensors to. What test specimen orientation should be used here? Treat it like a butt weld with a 3/16 butter layer and then the weld with the 2nd base metal?

If this forum is not the best place to ask this question, is there a more appropriate one?

Yes, see "Welding, Bonding & Fastener engineering" forum.
