Induction Pressure Welding

A welding process where joint interfaces of rotationally symmetric components are heated to forging temperature via an induction coil and subsequently joined permanently through axial upset pressure. This method is particularly suited for efficient mass production of automotive and powertrain components.

In induction welding, the coil heats the workpiece locally to forming temperature, then you press the parts together axially. The joint is formed by heat and pressure, not by melting. If the part cools too quickly, the steel becomes hard and brittle—you don't want that. Let it cool slowly and evenly, then the structure stays tough and crack-free. Make sure the pressure is applied cleanly and evenly, otherwise you'll distort the workpiece.
