Brazing (and Soldering)
Brazing and soldering are different than welding in that (like the metal version of hot-glue) only the filler metal is melted. The filler metal has a lower melting point than the base metal of the parts being brazed, and the parts are not heated to their melting point.
- Below 450°C (840°F) it's called soldering, and above that temperature it's brazing. (So-called silver soldering is actually silver brazing.)
- Brazing and soldering can be done with any heat source, but usually a gas torch for brazing and an electric soldering iron for soldering.
