Abstract
An inspection probe and system for inspecting a welded or brazed joint includes a housing having an internal cavity and opposed tapered standoffs disposed at a distal end portion of the housing. Distal ends of the opposed tapered standoffs define pivot surfaces, and the opposed tapered standoffs are spaced apart to define a secondary enclosure. A plurality of transducer elements are disposed within the internal cavity of the housing and a primary coupling medium made of a flexible, semi-solid material is secured between the opposed tapered standoffs. A signal processing module is in communication with a data acquisition unit, which is in communication with the transducer elements. The inspection probe is rotated across the joint, data from the transducer elements is communicated to the signal processing module, and reconstructed and corrected images obtained at different angles from the transducer elements are stitched to generate an inspection image.
