It's probably a silly question but is there any problem in quenching hot
soldered copper joints in water if feasible rather than waiting for them to
air cool before handling. I have been pre assembling some runs which I have
been quenching in water and now starting to wonder if the quenching may
cause some sort of failure / cracking in the solder due to the sudden
cooling. Hoping the question is as silly as I think it.
Won't hurt a bit once the solder has cooled enough to be out of the
plastic region. Be careful you don't get overanxious and start moving
stuff around before then though, you might mess up the quality of a
joint by having relative motion between the pieces at just the wrong time.
Same here, but quite often it was because the pipe and fittings were
being assembled in place between wood members, while standing on
ladders, scaffolds, etc. Not to say it's not okay but, I've never seen
a plumber 'immerse' sweated fittings in water after soldering.
Don't know if the same effect would be at work here but have you ever
dropped molten solder into water? (yeah, I was a dumb kid once). What you
end up with is something akin to solder wool. The solder expands from the
steam before solidifying. Might be a good way to generate pin holes.
