Induction Heating Glossary of Terms

Induction Heating: A process which is used to bond, harden or soften metals or other conductive materials, by placing the part   to be heated in a copper coil. For many modern manufacturing processes, induction heating offers an attractive combination of     speed, consistency and control.

Inductor: Specially-shaped copper tubing or other conductive material through which alternating electrical current is passed, creating a varying magnetic field. Depending on the application, the metal parts to be heated are either positioned close to the inductor or passed through it. But the parts are heated without actually touching the inductor.

Eddy Current:Circulating movement of electrical current within an electrical conductor caused by the intersection of the conductor with a moving magnetic field.

Heat Treating: A combination of controlled heating and cooling cycles applied to a metal for hardening or softening. Hardening, annealing, and stress relieving are examples of heat treating processes.

Quenching: Cooling a part with water after it has been heated.

Annealing: A process which softens a metal by first heating and then slowly cooling it. Annealing removes stresses and improves machineability.

Tempering: A heat treatment applied to a metal after it has been hardened. The metal is first heated and then rapidly cooled to   decrease hardness and increase toughness.

Brazing: A method of joining two pieces of heated metal together with a third, molten filler metal. Brazed joints have great tensile strength – they are often stronger than the two metals being bonded together.

Silver brazing: Joining two pieces of heated metal with a third, molten silver alloy. Silver brazing produces a very strong bond but requires very precise machining tolerances.

Soldering: the process of joining two pieces of metal by applying a third molten metal which has a lower melting point. Soldering is similar to brazing but it is done at lower temperatures and produces a less-strong bond.

Hot forging : It aims to strength the work pieces of certain temperature (different materials require different temperatures) into    other shapes through forging press with the help of punch press, forging machine or other equipments.

Shrink Fitting: The process of inserting a piece of metal into plastic. The metal is first heated, so that the plastic around the metal melts at first contact, and then cools around the metal, fing a firm bond [also known as heat staking].

Joule Effect: A scientific fula – also known as Joule"s first law – expressing the relationship between heat produced by electrical current passed through a conductor. It is expressed as "Q = I2 x R x t" where Q is the amount of heat produced, I is the current flow ing through the part (conductor), R is the electrical resistance of the part, and t = time.
