Solder can be had in a wide range of melting points, and above that you can
start in on brazing.

While I've not tried it, a DIY spot welder may be "easy enough" to do for
this task.

In the absence of enough thousands of uF  (or 1/1000th as nany mF if you
are Olin) then a car battery is liable to be useful. Could be fun trying
:-). May deep end on how much you value the pot :-).

It just occurred to me that it *MAY* be possible to produce a temperature
controlled spot welder that used eg a car battery as source and thermal
feedback for control. Presumably essentially on/off switching and "hot
enough"* completion.

* The dangers of slang: I used an idiomatic expression for 'hot enough' but
a quick web search showed that the meaning I had heard for it (ready to go
/ raring to go / ...) was #2 on some lists and not shown at all on others.
#1 was not what I intended :-(.
