.... 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...
