Abstract
A corrutherm expansion fixture is provided for supporting a part in a desired configuration during a brazing operation. The fixture includes a discontinuous corrugated ring formed from material which is expansible when subjected to high temperature. The fixture also includes a continuous inner ring and a discontinuous outer ring between which the corrugated ring is disposed. The inner ring resists inward movement of the corrugated ring when expansion force is exerted by the corrugated ring. The outer ring supports the part to be brazed and transmits the expansion force to the part to retain it in the desired configuration as the force is exerted on the outer ring by the corrugated ring.
