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.

Amorphous brazing foils are used for brazing, a metallurgical process by which two pieces of metal are joined by melting and cooling a third "filler metal" between them. The use of preforms increases the capability of ABFs for use on an industrial scale, aiding machine assembly.
The pin brazing process is well suited for joints between insulated pipe sections, connection to measuring cables, installation of sacrificial anodes and bonding zinc bracelets to offshore pipelines, due to the ease and speed of installation, high mechanical strength and extremely low resistance.

For successful soldering and brazing, the oxide layer has to be removed from both the surfaces of the materials and the surface of the filler metal preform; the exposed surfaces also have to be protected against oxidation during heating. Flux-coated preforms can also be used to eliminate flux residue entirely from the soldering process. [14]
