Abstract
An ultrasonic transducer device is provided which is used in ultrasonic inspection of the material surrounding a threaded hole and which comprises a wedge of plastic or the like including a curved threaded surface adapted to be screwed into the threaded hole and a generally planar surface on which a conventional ultrasonic transducer is mounted. The plastic wedge can be rotated within the threaded hole to inspect for flaws in the material surrounding the threaded hole.
Claims3
For use in performing an ultrasonic inspection of the material surrounding a threaded opening in a test device, an ultrasonic inspection apparatus comprising a wedge-like mounting member having a first, threaded surface which is adapted to be screwed into the threaded hole in the test object and a second, mounting surface;
- and an ultrasonic transducer mounted on said mounting surface, said mounting member being approximately semicircular in cross section and of a size such as to fit within the threaded hole in the test object and to leave space in said threaded hole for said ultrasonic transducer so as to enable rotation of said mounting member within said threaded hole and thus permit the orientation of said ultrasonic transducer relative to the threaded hole to be varied.
