resistance welding little spacers on a .093 wire? or other suggestions

resistance welding little spacers on a .093 wire? or other suggestions

resistance welding little spacers on a .093 wire? or other suggestions

(OP)
We used to put steel push nuts on this .093 inconel wire to hold these ceramic spacers in place... but they want to get away from the push nuts as they are hard to push on a 4' rod... the product gets up to about 1000-1200F so temp is a consideration... I was thinking about resistance welding a little round piece (like a BB) onto the rod on either side of the ceramic but I do not know if this is possible and if there is a semi cheap machine that could do this. I have seen little wire welding units in a thermocouple shop, not sure if a machine like this could work? There are about 8-10 spacers per rod so there would be a good number of welds... so it would have to be farely quick. Thank you for any suggestions.

Sounds like it would work.  Small spotweld unit...

try www.dcccorporation.com/hotspot.html

I've built my own before, for welding beads on really thin TC wire, out of junk electrolytic capacitors and a DC power supply.
