Brazing practice. Brazing is a metal-joining process in which two or more metal items are joined by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal. Brazing differs from welding in that it does not involve melting the work
Induction brazing is a process in which two or more materials are joined together by a filler metal that has a lower melting point than the base materials using induction heating. In induction heating, usually ferrous materials are heated rapidly from the electromagnetic field that is created by the alternating current from an induction coil .
When brazing cast iron, graphite must be removed from the surface to assure good wetting. May facilitate stress cracking of some alloys by liquid metal embrittlement; prior stress relief annealing is required then, or use of a higher melting point alloy that does not melt until stress relief temperature of the base metal is reached.
An amorphous brazing foil (ABF) is a form of eutectic amorphous metal that serves as a filler metal in brazing operations. ABFs are composed of various transition metals (including nickel, iron, and copper) blended with metalloids like silicon, boron, and phosphorus.
The American Welding Society (AWS) was founded in 1919 as a non-profit organization to advance the science, technology and application of welding and allied joining and cutting processes, including brazing, soldering and thermal spraying.

Pin brazing is a metallurgically safe [citation needed] method of making electrical connections [1] to steel and ductile iron pipelines [citation needed] as well as other metallic structures, [2] which are to be cathodically protected or electrically earthed.
