I'm working on an application where a flat piece with a manganese layer needs to be joined to a copper piece with projections on it ~.050 to .060 thk each. Two electrodes pinch the two parts with braze alloy 450 in between and pass current through to braze/weld the two pieces.

I'm getting a lot of variability in the joint. Bottom electrode is Tungsten, top copper. The part with the manganese layer sits on top of the copper piece.

ANYWHERE IN THE WEB THAT I CAN FIND INFORMATION ABOUT SIMILAR APPLICATIONS? I NEED TO GET A CONSISTENT WELD (PULL TESTS). THANKS.
