Induction heating is the process of heating an electrically conducting object by electromagnetic induction, through heat generated in the object by eddy currents. An important feature of the induction heating process is that the heat is generated inside the object itself, instead of by an external heat source via heat conduction. Thus objects can be heated very rapidly saving time and money. In addition there need not be any external contact. This process is ideal for ring/nut removal, expansion requirements and any specific target heating.
