ABSTRACT:
The present invention provides an apparatus for use in automated welding repairs, particularly those repairs intended for impellers and similar structures. In one embodiment, the invention provides an impeller weld restraining fixture. The fixture includes a base plate and top ring. An impeller may be sandwiched between the base plate and the ring mount. Tangs located on the top ring may be fitted to rest in the valley faces between airfoils on an impeller. Bolting the top ring to the base plate, with the impeller firmly secured therebetween, restrains the impeller so as to minimize warpage during welding repairs and heat treatments.
