Abstract

A method and apparatus for ultrasonically inspecting railroad rails (20) utilizing a plurality of ultrasonic roller search units (12, 14, 16). Each search unit is a liquid filled elastomeric tire containing one or more ultrasonic transducers (35, 75, O, Z). The liquid couples the ultrasound between the rail and each transducer. The spaced wheels are in rolling contact with the rails being inspected. The system utilizes a plurality of differently oriented beams (32, 34, 36, 40, 50) of ultrasonic energy from the transducers which are pulsed at different times for probing various regions of the rails being inspected. The transducers receive through transmission or pulse echo ultrasonic energy from the workpiece and use such information to determine the location and nature of defects in the rail.
