.... If the flux is liquid at the joining temperature, it has to wet the joint surfaces in order to be effective. A flux that is liquid can beneficially help suppress the volatilization of high vapor-pressure constituents of filler metals and thereby improve joint quality. This is particularly true in dip brazing...

... 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...

.... Unlike welding, brazing does not involve remelting of the base metal. In brazing, only the filler metal melts, and the joining of components is achieved via partial diffusion of filler metal into the base metal. Brazing filler metal, by definition, must melt above 450 °C (840 °F) and below the melting...
