Frequently Asked Questions

1. What is Induction Heating?

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, where eddy currents (also called Foucault currents) are generated within the metal and resistance leads to Joule heating of the metal. An induction heater (for any process) consists of an electromagnet, through which a high-frequency alternating current (AC) is passed. Heat may also be generated by magnetic hysteresis losses in materials that have significant relative permeability. The frequency of AC used depends on the object size, material type, coupling (between the work coil and the object to be heated) and the penetration depth.

2. What is Induction Hardening ?

Induction hardening is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without affecting the properties of the part as a whole.

3. What is Induction Forging ?

Inductech offers induction forge heating equipment used for heating a wide range of bar and billet diameters. Built to thrive in aggressive forging environments, the power supply in the InductoForge is the latest generation of an industrially proven system. The existing reliable technology is enhanced to provide unique features specifically benefiting the forgin industry.

4. What is Induction Melting ?

Induction melting is the process to melt the ferrous and non-ferrous metals for forming applications, tools & component casting and percious metal melting etc.

5. What is Induction Brazing ?

Induction brazing is a process in which two or more materials are joined together by a filler metal that has a lower melting point than the base materials using induction heating. In induction heating, usually ferrous materials are heated rapidly from the electromagnetic field that is created by the alternating current from an induction coil.
