  • Vacuum brazing: the guide to perfect brazed joints

    Apr 14, 2017· How vacuum brazing works. Brazing is a method of joining two or more metals by melting a filler metal, or the brazing alloy. When alloys are used instead of a pure metal for the process in a vacuum furnace, they do not contain fluxes, there is therefore no need to remove the slag by mechanical methods and the weld appears clean.
