Abstract
A scanner head for ultrasonic testing of structures includes a carriage with rollers supporting the carriage for movement over a surface being tested in a selected direction. A transverse frame is supported by the carriage and extends in a second direction crossing the one direction. A transducer is supported by the frame for movement along the frame to preset operative offset positions. For pipes or boiler tubes, the frame is in the form of an arc bar having a T-slot in which a holder for the transducer rides. With the carriage moving axially of the tube or pipe along a reference line, the arc bar keeps the transducer perpendicular to the surface regardless of the offset position. The rollers drive a distance increment signal generator to pulse the transducer and drive the ultrasonic transceiver and display circuitry.
