Clamps do not make as good a connection as exothermic welding (it isn't
soldering at all). Clamps loosen due to a variety of reasons, cold flow
of the conductors under the clamp being chief among them. Can't cold-flow
when you're welded ... maybe grow or shrink a bit!

Yes, your statement started more learning!
