Brazing

A method of joining non-ferrous metals using a non-ferrous alloy that melts at a lower temperature than that of the metal to be joined. Brazing is similar to soldering except that a higher temperature is required: in soldering, the non-ferrous filler metal melts below 800 Fahrenheit; in brazing, it melts above 800 Fahrenheit, but below that of the metals to be joined. Both of these processes differ from welding, where the base metals to be joined are heated until they flow together.
