Ultrasonic testing uses high frequency, highly directional sound waves to measure material thickness, find hidden internal flaws, or analyze material properties in metals, plastics, composites, ceramics, rubber, and glass. Using frequencies beyond the limit of human hearing, ultrasonic instruments generate shorts bursts of sound energy that are coupled into the test piece, and the instrument monitors and analyzes reflected or transmitted wave patterns to generate test results.
