Abstract:
1. A system for providing localized heat treatment of metal components, said system comprising: a non-oxidizing environment positioned about at least a portion of a component that is to be heat treated, the non-oxidizing environment being provided by an enclosure that is operative to receive a flow of gas such that oxygen is purged from about the component during heat treatment; a heating device having an infrared (IR) heating element operative to propagate electromagnetic energy in the IR spectrum responsive to an electrical input; a shield positioned to obstruct a line-of-sight between the IR heating element and an area of the component located adjacent the portion that is to be heat treated; and a gas purge line having an inlet positioned within the enclosure and being operative to draw out-gasses, generated by the heat treatment, from the enclosure.
