    5/829400

  • Abstract:
    Ultrasonic inspection apparatus is described comprising a linear array of contact ultrasonic transducers mounted on a carriage which moves over a surface to be inspected such that a relatively wide path is inspected as the carriage traverses the test surface. The contact transducers arranged in a transmit-receive-transmit mode detect variations in surface sound wave velocity resulting from impact damage to the surface being inspected. When a damaged area exceeding a predetermined area is detected, one of a plurality of indicator lamps associated with the receive transducer is momentarily energized. In addition, when a defect is detected by any one of the receive transducers, a master indicator lamp is energized for a relatively long period of time in order to signal the operator that one of the transducers in the array has sensed a defect. Thus, if the operator has not noticed the momentary energization of one of the lamps associated with a single receive transducer, he will nevertheless notice the master indicator and can then retrace the path of travel of the carriage to precisely locate a defect by observing the separate indicators for each receiving transducer.
