ABSTRACT:
A damaged turbine rotor wheel dovetail is repaired by cutting off the annular dovetail and welding a new forged ring onto the remaining wheel body. Fine-line welding is accomplished by inserting welding apparatus into grooves opening through axial faces of the wheel body and ring and rotating the rotor to provide multiple welding passes. Periodic ultrasonic inspection of the welds is provided by applying an ultrasonic transducer to the periphery of the ring to detect defects in the weld. To enable the transducer to operate at high welding temperatures, a manifold is disposed about the transducer defining a coolant cavity. Cooling medium is supplied the coolant cavity to maintain the transducer operable within predetermined temperature operating limits.
