ABSTRACT:
A welding fixture is disclosed for temporarily retaining two tubular workpieces relative to one another. The welding fixture includes a plurality of shoe assemblies, each of the shoe assemblies being radially movable between a contracted position and an expanded position. The welding fixture further includes an actuator operatively connected to each of the shoe assemblies for selectively moving each shoe assembly between the contracted position and the expanded position. Upon expansion of the shoe assemblies, the welding fixture is operative to reinforce and temporarily retain a joint formed between two tubular workpieces during a joining procedure, such as welding.
