Abstract

A device for induction heating of a workpiece (4) has two separate bodies (1). Each body (1) comprises at least one pole (6) and a coil (7) arranged round each pole (6). The device further has a voltage source (8) connected to said coils (7) for generating a magnetic field in and round the poles (6). The bodies (1) are arranged on each side of the workpiece (4) with opposite poles (6). The device also comprises a control unit (9) which is adapted to provide a variable phase difference between the currents flowing through the coils (7) of the opposite poles (6), thereby varying the penetration depth of the generated magnetic field in the workpiece (4) or a tool (3) enclosing the workpiece (4).
