  • Matrix phased array system for ultrasonic inspection of brazed welds
    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.
