The weld surface is pretty clean; the parts come directly from a punch process and there is generally no contamination in the area. Soot builds up on fixturing that is in close contact with the weld zone. I have tried to simulate the problem with process related contamination but have not been...
Looking for ideas on root-cause for laser-weld defect:
Currently, we are seeing small voids approximately 5-10% of a 0.016" weld spot. The process involves welding several SS parts together; the issue is not porous, as we only see one, two at most, voids in one 0.4" weld pass. The voids do...
