Hello all, been reading for a while, finally have a question.
We are looking at welding some rare alloy per QW-193. Unfortunately due to the PM when the mill has our tubes ready for fabrication, we need our WPS ready. So there is no tube available for testing, but there is sheet available.
Would it be appropriate (I prefer a code interpretation or other reference) to use rolled sheet with tacks and insert this into the tubesheet mock-up block in place of code spec tubes, then do our normal QW-193 development? I'm confident it will produce reliable results and catch any issues in the weld, but the code says nothing except "essentially duplicate".
