Abstract: A testing apparatus, inspection system, and method for through-transmission ultrasonic testing. The testing apparatus includes a yoke having a support member with a pair of hinge joints, each hinge joint located on an end of the support member; a pair of arms extending from the support member having a hinge end and a pivotable transducer end, each arm being coupled to the hinge joint at the hinge end and extending to the pivotable transducer end; a pair of transducer support members disposed on each of the pivotal transducer ends; and a tension member connected to the pair of arms for aligning the pair of transducer support members during testing.

Abstract: A method of inspecting a component using a film overlay including providing the component, the component having a first surface, a core, and a second surface; positioning a film overlay having a reference indicia and a structural indicia on the first surface of the component; aligning the reference indicia on the film overlay with a reference feature on the component; positioning a testing probe on a top surface of the film overlay so the probe is aligned with the structural indicia; and transmitting a signal from the probe through the film overlay, the first surface, the core, and the second surface.
