	WELDERS TURN TO INDUCTION HEATING FOR PREHEATING, STRESS-RELIEVING
		Induction heating's similarity to resistance heating is that conduction is required to heat through the section or part.
		Induction heating is also safe, reliable and easy to use, and scores higher than alternative technologies in power efficiency and versatility.
		Induction heating was able to shave two hours off the time-to-temperature (600 degrees F) and another hour to reach soak temperature (600 degrees F to 1350 degrees F) for stress relieving.

	Induction heating - Wikipedia, the free encyclopedia
		Induction heating is the process of heating a metal object by electromagnetic induction, where eddy currents are generated within the metal and resistance leads to Joule heating of the metal.
		Induction furnaces are used in most modern foundries, as a cleaner method of melting metals than a reverberatory furnace or a cupola.
		Induction heating is often used in Induction sealing or "cap sealing".

	Induction Heating Theory And Principles
		Induction heating is a process which is used to bond, harden or soften metals or other conductive materials.
		Induction coils are normally made of copper tubing - an extremely good conductor of heat and electricity - with a diameter of 1/8" to 3/16"; larger copper coil assemblies are made for applications such as strip metal heating and pipe heating.
		Induction coils are usually cooled by circulating water, and are most often custom-made to fit the shape and size of the part to be heated.

	Induction bolt heating - Bolttech
		Induction heating occurs when a material capable of conducting electrical current, not necessarily ferrous or magnetic, is placed in a varying magnetic field.
		This effect enables induction heating to be used with non-magnetic and slightly magnetic materials such as 422 Stainless Steels, commonly used for internal components for high temperature inner turbine casings and bolting.
		Simply stated, the induction heating coil acts as a primary side of a transformer and the bolt acts as a secondary side, with the eddy currents flowing around within the mass of the bolt.

	PowerLabs induction heating!
		The concept of heating without any physical contact: induction heating, has been around for over 40 years and finds use in almost every industry where metals are used, be it in alloying, metal forming, tempering, hot working or shrink fitting.
		The basic principle behind heating by induction is that a very strong rapidly alternating magnetic field will induce eddy currents on any conductive material placed in the vicinity of that field.
		It resembles the first induction heaters ever created in that the high magnitude alternating current pulses are created on it by means of a spark gap switched RCL circuit, no different from a Tesla Coil.

	Induction welding - Wikipedia, the free encyclopedia
		Induction welding is a form of welding that uses electromagnetic induction to heat the workpiece.
		In an electrically conductive workpiece, such as steel, the main heating effect is resistive heating, which is due to magnetically induced currents called eddy currents.
		In a ferromagnetic workpiece, such as plastic doped with ceramic particles, the heating is caused mainly by hysteresis as the magnetic component of the electromagnetic field repeatedly distorts the crystalline structure of the ferromagnetic material.
