A expansion joint, or movement joint, is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials. They are commonly found between sections of buildings , bridges , sidewalks , railway tracks , piping systems , ships , and other structures.
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.
One of the main disadvantages is the lack of joint strength as compared to a welded joint due to the softer filler metals used. [1] The strength of the brazed joint is likely to be less than that of the base metal(s) but greater than the filler metal. [5] Another disadvantage is that brazed joints can be damaged under high service temperatures. [1]
Modified nickel-silver. Moderate-strength, tough. Excellent plasticity in molten state. Gap-filling. Excellent strength and ductility during cooling, which is an advantage over silver brazes when joining materials with dissimilar thermal expansion. For carbides, stainless steels, tool steels, and nickel alloys.
The joint is then heated, typically by using a propane or MAPP gas torch, although electrically heated soldering tools are sometimes used. Once the fitting and pipe have reached sufficient temperature, solder is applied to the heated joint, and the molten solder is drawn into the joint by capillary action as the flux vaporizes. "Sweating" is a ...
