brazing, method of joining metal parts using nonferrous filler metals with high melting points such as copper, silver, and aluminum alloys. Brazing differs from soldering (see solder) by using a higher temperature; and unlike welding, the parts are not melted. Brazing is best for dissimilar or thinner metal parts and for parts difficult to weld or solder.
