What is Ultrasonic Testing (UT)?

Ultrasonic Testing (UT) is a non-destructive testing method that uses high-frequency sound waves to detect flaws or measure material thickness. A transducer emits sound waves that travel through the material and reflect back from interfaces, such as cracks or the back wall. By analyzing the amplitude, time-of-flight, and other characteristics of the reflected waves, information about the size, location, and nature of the discontinuities can be determined. UT is commonly used for weld inspection, thickness gauging, flaw detection in metals, composites, and other materials, and for characterizing material properties.
