ABSTRACT:
An improved heat treatment fixture is disclosed formed in a tubular frame network structure composed of mating plural cylindrical tubings segments and cast couplings which are interconnected by pins to permit moderate movement within the frame network structure during the heat treatment process, and thereby. relieve thermal stresses developed within a fixture. The tubing frame network structure renders the fixture lightweight and is adapted to permit multiple fixtures to be rapidly linked together in an end to end orientation to vary the size and capacity of the fixture. The fixture is further constructed to allow rapid repair by the end user to prolong the useful life of the fixture and includes a part tray which is replaceable directly within the field.
