Induction heating is a process which is used to bond, harden or soften metals or other conductive materials. For many modern manufacturing processes, induction heating offers an attractive combination of speed, consistency and control.
Induction heating is the heating of electrical conducting parts in a varying magnetic field. Induction heating (or melting) takes place when an electrically conductive object, not necessarily magnetic, is placed in a varying magnetic field. This can be illustrated by connecting a copper coil or inductor to an alternating electrical supply.
