Exothermic brazing is a process that utilizes the heat produced in a solid-state chemical reaction to melt a conventional filler metal or to produce molten filler metal as a product of the reaction. This article provides the pros and cons of exothermic brazing, describes procedure of the process, and illustrates a typical arrangement for the exothermic brazing of tube. It provides information on the exothermic compounds used for brazing refractory metals and aluminum alloys.
