Continuing to think of what material to use for vise jaws. I have some
electrical copper bars, looks like 3/16 thick, that would work for
soft vise jaws.
To keep them on the vise, I could weld some copper to the back to look
like "ears" to hold the jaws.
So, obviously, the strength requirements are minimal. Just keep the
jaws from falling off when the vise is opened.
The question is, can this electrical copper be welded at all.
DC TIG

Mr. Minnick says it can. Mechanical clean, degrease, preheat with
oxyacetylene and pump a mess of current in. Everything but leaded brass
is rated at fair to good weldability. He recommends argon/helium mix for
the heat.
From "Gas Tungsten Arc Welding Handbook" by William H Minnick, My
favorite TIG refence book which is where I start with questions like this.
Good Luck,
Bob

Mr. Leimkuhler is my first go-to reference:

It would certainly be easier to simply soft or hard solder the
attaching ears onto the copper.... wouldn't it?

No disagreement from me about Ernie being an excellent reference.
Maybe because I am getting to be an aging dog, the net is not my first
stop.
Especially for what should be readily available info that has not
changed in
the last decade or three.
