ABSTRACT:
Method and apparatus for making a roof of a water-steam cooled cyclonic separator. The fixture locates, supports, and restrains portions of the roof during welding operations. By continuing that restraint through a stress relief step, the method and apparatus address the problem of distortion that otherwise would occur during welding. The method and fixture provide good access to the roof during the welding operations and, in particular, allow for faster welding and welds of higher quality by maximizing the availability of "down hand" welding techniques. The fixture is a universal fixture, designed to accommodate roofs of varying geometries.
