Not having any formal training in metalworking, I end up having to figure out a lot by myself as I go – often the hard way. I learned a lesson today when I came to a project that required me to braze a piece of stainless steel pipe to another piece of steel.
I got it to work with my oxyacetylene torch and flux-coated bronze brazing rods, but it was ugly, uneven, and popped and sputtered as I was doing it. I really wondered why, so I looked it up online. It seems that it’s best to use a special kind of flux along with a silver-based brazing rod when you’re working with stainless. Good to know!
