<p>A heating apparatus (10) and method for welding a superalloy article are described. The apparatus (10) and method provide for pre-welding and post-welding heat treatments to be performed on an article within the same enclosure (12) in which the welding operation is performed. The apparatus (10) accurately controls the temperature of the component to be welded throughout the temperature treatment profiles with the use of means for welding the article, means (14) for heating the article within the enclosure (12), and means (24) for sensing the article temperature. The apparatus (10) also works in conjunction with a memory storage device that stores appropriate pre-weld and post-weld heat treatment temperature profiles and a welding temperature profile for the article. <IMAGE></p> |
