ABSTRACT:
This invention refers to an ultrasonic pulse-echo nondestructive test method and apparatus for causing the axis of an ultrasonic energy search beam path transmitted from an ultrasonic transducer probe to a workpiece to be maintained normal to an irregularly contoured workpiece entrant surface. Electrical circuit means measure and compare the echo signals reflected from the workpiece and cause the search probe to be positioned to maximize the amplitude of the received signals.
