There are three main categories of torch brazing in use: [10] manual, machine, and automatic torch brazing. Manual torch brazing is a procedure where the heat is applied using a gas flame placed on or near the joint being brazed. The torch can either be hand held or held in a fixed position depending on whether the operation is completely ...
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 .
Wire wrap was used for assembly of high frequency prototypes and small production runs, including gigahertz microwave circuits and supercomputers. It is unique among automated prototyping techniques in that wire lengths can be exactly controlled, and twisted pairs or magnetically shielded twisted quads can be routed together.
Brazing has the advantage of producing less thermal stresses than welding, and brazed assemblies tend to be more ductile than weldments because alloying elements can not segregate and precipitate. Brazing techniques include, flame brazing, resistance brazing, furnace brazing, diffusion brazing, inductive brazing and vacuum brazing.
For most metals, incl. stainless steel and carbides. Highly recommended. Recommended for 300-series stainless steel. Good for food-handling applications with close joint tolerances. Gap 0.1–0.25 mm. Alloy specifically designed for brazing tungsten carbide tips to steel tools and wear parts. Readily wets nickel and iron alloys.

Fruitcake. Step one of a fruitcake is soaking pounds of dried fruit until it's plump and filled with bourbon. That takes up to 12 hours. Step two is simple: making and baking the loaves.
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.
