ABSTRACT:
An apparatus for ultrasonic inspection of polyethylene-jacketed, cast expive billets including an immersion tank and a roller system for axially rotating the billet while immersed in the coupling fluid. A drive mechanism traverses a pair of laterally opposed transducers axially of the rotating billet for through-transmission inspection of the majority of the billet. A second drive mechanism sweeps a third transducer through a 90.degree. arc for pulse-echo inspection of the hemispherical base of the billet.
