Silver soldering.

Postby David Gladwin » Fri Oct 05, 2018 9:01 am

Some advice please.

For silver soldering I had a superb device in Australia, just right for small silver soldering using a propane and oxygen mix.

I can’t get the oxygen bottles in U.K so could I ask what you guys use in the U.K. for silver soldering jobs.

Propane torches just don’t seem to work for me, and the silver soldering Iwant to do is on critical parts so I want to use plenty of heat.

Any help would be appreciated.

David.

Hi David, I've just seen this query but I can advise on the method I employ when silver soldering. It's very Heath Robinsonish but works very effectively, I apply a background heat from a gas torch used by roofing workers from a butane botttle and then apply a local high heat from a propane/butane torch as used by plumbers. I've made up many silencers and exhaust manifolds from this method and also very fine work as well. Get some old house bricks as a working platform and also to shield the area and off you go from there. The background heat source brings up the worked piece to a good heat and then the localised source will get the piece up to cherry red very quickly. Hope this helps.
I am going outside, I may be some time.
