ABSTRACT:
A method of non-destructive evaluation (NDE) testing a component of an assembly is provided. The method includes positioning a transducer on a face of the component, transmitting ultrasonic waves into the component at a plurality of steering angles, receiving ultrasonic echoes, wherein each received echo is indicative of an acoustic impedance interface within the component, and analyzing the ultrasonic echoes.
