Abstract:

This patent describes an apparatus for ultrasonic inspection of polyethylene-jacketed, cast explosive 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 deg arc for pulse-echo inspection of the hemispherical base of the billet. Author
