Induction Heating

Description

ASM International has developed this course covering the entire spectrum of induction heating technology. Written by industry experts, it covers the role of induction heating in producing reliable products, often with considerable savings in energy, labor and time.

Taking a fundamentals approach, the basic principles of induction heating are presented as an introduction. With this as background, methods of selecting equipment, frequency, and power; designing coils; and installing such as heating prior to hot working, heat treating, welding and brazing and melting are described in depth. A lesson on special applications, particularly those involving non-metals, is included to illustrate the wide range of uses of induction heating. The final lesson deals with the important questions of system safety and process economics.

This course was developed in cooperation with the EPRI Center for Materials Fabrication. A scientific calculator is required for this course.

Target Audience

Process, electrical, and manufacturing engineers, as well as heat treating personnel will benefit from this course. Technicians, metallurgists, design personnel, industrial engineers and methods analysts will also derive value from this course. Some exposure to basic electrical concepts is desirable.

Required Pre-Requisites

A strong mathematical background.
