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 pieces. Brazing differs from soldering through the use of a ...
DeWalt Ford Fusion in 2008, driven by Matt Kenseth. DeWalt Tools sponsored NASCAR driver Matt Kenseth from 1999 through to the season of 2009. In this time period, Kenseth won 18 races, the 2000 Sprint Cup Rookie of the Year Award, 2003 Winston Cup Series Championship, 2004 NEXTEL Cup All Star Race and the 2009 Daytona 500.
Active alloy. Can be used for brazing ceramics, metal-ceramics, graphite, diamond, corundum, sapphire, ruby. Needs at least 850 °C for wetting ceramics, higher temperatures improve wetting. For use under argon or vacuum, in vacuum silver may evaporate above 900 °C. 19.5: 72.5: 3: In 5: Ag 96 Ti 4: active 970 [98] – BrazeTec CB2. Active alloy.
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.

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 .
Soldering and brazing are thought to have originated very early in the history of metal-working, probably before 4000 BC. [2] Sumerian swords from c. 3000 BC were assembled using hard soldering. Soldering was historically used to make jewelry, cookware and cooking tools, assembling stained glass , as well as other uses.
Brazing is a joining process in which a filler metal is melted and drawn into a capillary formed by the assembly of two or more work pieces. The filler metal reacts metallurgically with the workpieces and solidifies in the capillary, forming a strong joint. Unlike welding, the work piece is not melted.
