Induction brazing is a heating process that uses an electromagnetic field to heat the parts and filler material to be joined. It is often used for brazing copper fittings and pipes for water heaters, as it offers many benefits such as speed, efficiency, safety, and precision1. Induction brazing can also be used for other metal combinations, such as steel, brass, aluminum, and carbide.
To perform induction brazing, you need an induction heating system that consists of a power supply, a coil, and a water cooling system. The power supply generates an alternating current that flows through the coil, creating a magnetic field. The coil is designed to fit the shape and size of the parts to be brazed. The parts are placed inside or near the coil, and the filler material is applied to the joint area. The magnetic field induces eddy currents in the parts, which generate heat through electrical resistance. The heat melts the filler material and forms a strong bond between the parts.
Induction brazing has many advantages over other heating methods, such as torch brazing or furnace brazing. Some of these advantages are:
