Induction heating is used to apply heat to mating components to melt a filler metal placed around or between the joint which then coats and bonds the components in the region of the joint. Commonly used filler metals are tin-lead, tin-silver, and tin-zinc. Induction heating can eliminate cold joints, protect insulation materials in close proximity to the joint since they are not heated by the induction field, and in some case even provide a stirring action and promote solder flow in connectors. Soldering is used in many joining applications but is used most often for high quality electrical connections which can then resist joint degradation and loss of conductivity due to corrosion or vibration. Soldering is also used in operations where non metallic components are joined to metals.

A thermocouple well is brazed using a single turn induction coil which allows the assembly to be slid into brazing position and then removed.

A large carbide cutting tool is brazed using an induction coil which is shaped to provide equal heating of the holder and the carbide.

An ORFS hex fitting is silver brazed using a Heat Station 5000 unit and quick-change.

A copper tube is silver brazed into a brass casting using a ceramic coated shaped coil. This allows the large mass of the casting and the light tube to be heated uniformly.

A graphite disc is heated with induction using a foot pedal style variable control. The disc is machined to locate a PCD and small holder. It is difficult to butt braze with other methods.

Three steel tubes are brazed simultaneously to a tee connector using internal brazing rings and an open style U shaped coil for ease of insertion and removal of parts.
