A phased array ultrasonic testing system for examining discontinuities in turbine or generator rotor bores formed within turbine or generator rotors of a turbine or generator rotor assembly. The system includes a phased array ultrasonic transducer structured to be coupled to a surface of the rotor bore at a first location in order to emit an ultrasonic beam toward a second location of the rotor bore which is to be examined. The system further includes a control system with a computer and a controller for programming, emitting, and steering the ultrasonic beam via at least one, two-dimensional phased array transducer, thereby precisely and accurately inspecting the area of interest. Computer control of the beam permits the number of inspection locations and the number of different transducer wedges to be reduced providing for an efficient, timely inspection.
A phased array ultrasonic testing system for examining a rotor bore formed within a rotor of a turbine or generator rotor assembly, the rotor having an interior surface and an exterior surface, the interior surface serves as a surface of the rotor bore, the phased array ultrasonic testing system comprising:
A method of ultrasonically examining a rotor bore formed in a rotor of a turbine or generator rotor assembly, the method comprising:
