Abstract
An induction heating system that can be used to braze metals and that overcomes many of the disadvantages of conventional brazing systems. The induction heating system improves quality and lowers production cost for many brazing requirements. The system is designed to quickly, accurately and cost effectively heat individual parts, and to replace flame brazing procedures and batch vacuum furnaces. Because the system can braze parts in an inert atmosphere or in no atmosphere (e.g., in a vacuum), no flux or acid cleaning bath is necessary and oxidation on the part is eliminated. Further, by including a gas quenching feature, the system prevents the annealing of parts and produces high quality brazed parts that meet desired hardness specifications. In one embodiment, the induction heating system includes a vacuum chamber; a support surface located within the chamber for providing a surface onto which a part to be heated is placed; moving means connected to the support surface for moving the support surface within the chamber; a vacuum system connected to the chamber for exhausting gases from the chamber; an electrically conductive coil located inside of the chamber or located adjacent …
