Hi,
Some manufacturers qualify welders using carbon steel base metal, in lieu of stainless base metal, with SS filler".
How about requirement of QW301.2 "the performance qualification test shall be in accordance with qualified WPS or SWPS"?!
BR,

If the code mandate to make kind of tests on the material and the client refuse to make this tests.
What should a contractor do?
Does he respect the code or the client!?
