We want to do process qualification with the new 0.035 wire to finalize the parameters of the machine. We would like to do etch test on the welded sample to see penetration.
What is the sample length we should have to do process qualification ? are there any standards ?
If your project specification does not reference a welding standard, you can adopt one. AWS B2.1 (not my favorite welding standard) can be used to qualify your procedures. It is not a fabrication standard.
