I wonder how practical it is to weld test leads, so there's no solder or
thermal EMF.

I know that this will sound crazy, and probably is, but could one weld
components to a PCB?

I don't even have the excuse of been drunk or taking drugs,  but I will
risk ridicule for making the above comment!  Sometimes thinking out of the
box is useful.
