History and Applications
Electromagnetic induction is a way to heat electrically conductive materials such as metals. This article provides a brief history of electromagnetic induction and the development of induction heating technology. It explores various applications such as heating prior to metalworking, heat treating, melting, joining (welding, brazing/soldering, and shrink fitting), coating, paint curing, adhesive bonding, and zone refining of semiconductors. The article also discusses the advantages of induction heating.
