After a few months of trial and error we finally became consistent with testing foil welds!  I have added some photos of the new successful pieces.  This was all tested to D17.2 resistance seam weld code.  Thank you for all who put in input on the testing equipment.

What are those components being made for? What kind of pressure are you going up to?
