Abstract
A system and method that allows for the immersion ultrasonic inspection of test samples that cannot be immersed in a fluid (e.g., water) bath. A test sample is encapsulated in a sealed evacuated bag made of nonporous flexible material. A portion of the nonporous flexible material is in contact with the surface area of the test sample where the ultrasound wave or beam will impinge. Then the sealed bag with test sample inside are immersed in an acoustic coupling medium, as is an ultrasonic transducer. The transducer is directed to transmit an interrogating ultrasound wave or beam through the vacuum bag into the component being inspected at the area of interest. The sealed bag prevents contact between the inspected component and the acoustic coupling medium.
