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 .
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.
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.
Aluminum wire used before the mid-1970s had a somewhat higher rate of creep, but a more significant issue was that the same high price of copper driving the use of aluminum wire led to the use of brass-coated steel rather than solid brass screws for terminations at devices such as outlets and switches.
German investigators suspect a Berlin doctor of killing eight elderly patients under his care and setting fire to some of their homes to cover up his crimes, prosecutors said Thursday.
