... Oxyacetylene braze welding is a method of oxyfuel gas welding capable of joining many base metals, but it is used primarily on steel and cast iron with a copper alloy filler metal (rod) and a flux. Braze welding is similar to torch brazing with a filler rod, except that joint openings are wider...
