Tig Brazing Copper To Stainless

If you are tig welding copper buy oxygen free copper.

Tig brazing copper to stainless. But remember its not as strong as a weld. It is different than steel but it is straightforward enough. Brazing is done at lower temperatures without melting the base metals. Pay attention to those and your project will be fine.

But because of its low melt point silicon bronze tig brazing works better on galvanized sheet than welding with mild steel rods. 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. The filler material flows into any and all microscopic crevices in the metal and pulls the pieces together similar to a permanent velcro. My client is presently silver soldering these butt joints but that is pretty expensive.

This is the copper to stainless butt after welding. The little details are various. Silicon bronze will join carbon steel copper bronze brass cast iron pretty much any of these to any other. Tig welding copper is not hard but it doesn t get done that often.

I use the term silver brazing instead of silver solder because technically anything over 840 degress f is brazing. You can t treat copper like steel.

I would like to know if it is possible to tig weld copper pipe fittings to 300 series stainless steel. Browse suggested weld parameter settings for tig welding. Buy the right copper. Silicon bronze rod has a melting temp of around 1050 c while stainless steel has a melting point of 1400 1450 c.

So here is the video with a few tips on silver brazing copper to steel and brazing stainless steel bolts to some copper washers.
