Abstract
An ultrasonic testing assembly structured to examine a test object, wherein the test object has a surface, and the examination examines the structure of the test object under the surface as well as the profile of the surface. The ultrasonic testing assembly includes a sled assembly structured to support a plurality of ultrasonic transducers, the sled assembly including at least one support member having a lower surface, at least one surface ultrasonic transducer coupled to the sled assembly and structured to extend below the support member lower surface and further structured to engage the test object surface, the surface ultrasonic transducer structured to examine internal structure of the test object and provide a first output, at least one profiling device coupled to the sled assembly, the profiling device structured to measure the profile of the test object surface and provide a second output, and a control device structured to correlate the first output and the second output and to calculate a corrected output.
