Qualification of hard facing clad under ASME section IX bend tests?
Qualification of hard facing clad under ASME section IX bend tests?
(OP)
Our contract welder is insisting that for our hard facing (625 onto 316) weld clad that we have to have a butt weld tension and root & face bend test? My understanding under section 9 is that we can test the clad in bend and this is acceptable, it seems a butt weld (316-316 using 625 filler) is not relavent or neccesary. I think I may be wrong?
Secondly is the bend former limtied to 2T as the welder has specced to the test house to use 4T, at 180, can we not sepcify this - ie 4T at 90 or 2T at 90?
Thirdly this has all been carried out on tube as the final product will be tube, but is it possible that we can use plate of the same thickness, I can't seem to find any guidance in section 9 about this.

Hard surfacing procedure qualifications do not require bend testing.
