The generator transforms the mains current into another current with a frequency suitable for the treatment to be carried out.

During industrial production, heat treatment is a key process, that can give specific properties and strength to workpieces. However, the heat treatment process is not always smooth sailing. Various defects often occur.

Annealing is a heat treatment process in which steel is heated to a temperature above or below the critical point AC1, and then slowly cooled with the furnace after a certain period of heat preservation to obtain a near-equilibrium state structure.

Induction brazing is to place the metal work piece to be welded (usually copper is mostly) in an High frequency induction heating machine coil, pass high-frequency alternating current to generate an induced electromagnetic field,

For the workpiece subjected to torsion, bending and other alternating load, the surface layer is required to bear higher stress or wear resistance than the core, so the surface of the workpiece needs to be strengthened, suitable for carbon content We=0.40 ~ 0.50% steel;

In order to achieve uniform heating depth, different parts of the workpiece need different frequencies during heating when heating the surface of non-uniform cylindrical devices.
