Discovered TIG brazing about 17 years ago when building a “special” tool to reach the exhaust side turbo mount nuts in a 300 ZXtt with upgraded pinwheels. Attached a socket to the side of an extension to make something similar to a box end crows foot. Grabbed the wrong rod and started welding I thought. As I watched the puddle I remember thinking that flows like brass..... l looked at the rod when I finished, obviously it was brass rod. Learned something new then!

Alternative from the HVAC industry...for brazing...with OxyAc.
Probably also TIGABLE, but look it up to be sure.
GaryC83 said:Silicon bronze is ideal for welding header tubes to the flanges on the exterior joint. Gives it a little bit of flexibility and strengthens the joint right up. We do it on all our headers as well as turbo manifolds. Everything is full back purged and welded with stainless filler everywhere else, including the head side of the flange. The exterior joint is the only spot that gets silicon bronze.
We use it for a bunch of other stuff too, like certain situations where seam welding a chassis - similar to how a lot of factory backed motorsports and WRC shells are prepared, and filling/ smoothing seams. In the right application, its great.
There's a bunch of it in the bay I'm working on now. Tying everything together and tidying things up at the same time.
It looks like it sands up nice as a filler for areas that are welded and ground. And looks like it would keep you from grinding away too much base metal at the joints. Plus no polyester filler.
That is beautiful , thanks for showing it
