ABSTRACT:
A method and apparatus for conducting ultrasonic inspections of what would normally be inaccessible areas of objects for such properties as thickness, cracks, discontinuities, density, pits and holes. In addition, a method and apparatus for improving ultrasonic inspections with a method for removing trapped gasses from the couplant. Also, a method and apparatus for conduction ultrasonic inspections of objects for multiple properties such as thickness, cracks, discontinuities density, pits and holes with at the same time with a single transducer. Further more, a method and apparatus for conducting rapid ultrasonic inspections of concave surfaces of objects for multiple properties such as thickness, cracks, discontinuities density, pits and holes with a single transducer. This invention allows for the inspection of the entire surface of the object or specific defined areas.
