Abstract
A system for induction heating of workpieces which are transported touching or in close proximity through a succession of inductor coils along the workpiece axes. A grounded feeder supplies workpieces to the transporting structure and a grounded further processing machine receives the workpieces after heating. To eliminate sparking and corrosion problems, the AC currents fed to the coils are adjusted, for example by feeding currents in phase opposition to different coils, so that the potential along the direction of the workpieces from the first to last coil is substantially zero.
