  • Patent number: 10234426
    Abstract: A system for non-destructively inspecting brazed joints that includes at least one matrix phased array probe that further includes plurality of ultrasonic transducer elements arranged in an array at one end of the probe, wherein the transducer elements are operative to both generate ultrasonic signals and to receive reflections thereof; and at least one tip adapted to be removably mounted over the array of ultrasonic transducer elements, wherein a region of the at least one tip has been shaped to correspond to the geometric characteristics of an item or a specific portion of an item that includes a brazed joint to be inspected; and a processor running software that includes at least one imaging algorithm for processing data received from the at least one matrix phased array probe and generating color coded ultrasonic C-scan images of inspected brazed joints.

  • Publication number: 20180266993
    Abstract: A system for non-destructively evaluating components fabricated by additive manufacturing processes that includes a sensor array embedded within an electromagnetic field concentrating material or matrix, and that includes a plurality of individual elements arranged in a predetermined pattern for allowing substantially uniform coverage of an area of an electrically conductive component to be evaluated; wherein each element in the plurality of elements further includes at least one coil that acts as an exciter coil for generating an alternating electromagnetic field when activated, or a receiver coil for measuring a change in impedance of the at least one coil, or as both an exciter coil and a receiver coil; wherein the alternating electromagnetic field induces eddy currents in the component to be evaluated; and wherein the individual elements in the sensor array are excited in a predetermined sequence during a single pass of the sensor array over the area of a component to be evaluated.
