Tig brazing copper to stainless.

But because of its low melt point silicon bronze tig brazing works better on galvanized sheet than welding with mild steel rods. Now technically this would be classified as tig brazing because the stainless steel has a higher melting point then the silicon bronze filler rod. Pay attention to those and your project will be fine. You can t treat copper like steel.

Tig welding copper is not hard but it doesn t get done that often. The gold look of silicon bronze makes stuff look cool. It is different than steel but it is straightforward enough. So here is the video with a few tips on silver brazing copper to steel and brazing stainless steel bolts to some copper washers.

Brazing is done at lower temperatures without melting the base metals. If you are tig welding copper buy oxygen free copper. Silicon bronze rod has a melting temp of around 1050 c while stainless steel has a melting point of 1400 1450 c. The little details are various.

Browse suggested weld parameter settings for tig welding. Silicon bronze will join carbon steel copper bronze brass cast iron pretty much any of these to any other. The filler material flows into any and all microscopic crevices in the metal and pulls the pieces together similar to a permanent velcro. I would like to know if it is possible to tig weld copper pipe fittings to 300 series stainless steel.

But remember its not as strong as a weld. The brazing alloys and fluxes are available at most hvac r suppliers and if the guy at the counter. Because of this you don t need the base metals to be similar so it s possible to tig braze copper to stainless steel as an example. My client is presently silver soldering these butt joints but that is pretty expensive.

Buy the right copper.
