I'm not proffessing expertise in welding specification, but it would seem to me that the usual crimp connection afforded by audio terminations is not a true cold weld (vacuum, pressure, etc.)
At any rate once a connector is attached it still goes through another pressure fit connection of some 'modest' pressure.
As an aside looking at construction techniques employed in vintage analog test equipment (tektronix etc.) is fun.
