Abstract
A method and apparatus for in-situ induction tempering is provided in which an induction coil is used to temper a part in-situ at the location. The use of an induction coil in-situ at the heat treating location eliminates the need (and time and expense) of a multi-step process wherein in part to be tempered would otherwise have to be moved from the quenching location to the tempering location, such as at a tempering furnace. It also eliminates the need for the tempering furnace, which is a great space savings. In one form of the invention, the power supplied to the induction coil is controlled by a closed-loop temperature controller that is controlled by the temperature in the vicinity of the tempered part, as opposed to simply be controlling on time at temperature.
