Ultrasonic Testing (UT)

Ultrasonic Testing is the process of transmitting high-frequency sound waves into a material to identify changes in the material’s properties. In general, UT uses sound waves to detect defects or imperfections on the surface of a material created.

Common Ultrasonic Testing methods

One of the most common UT methods is the pulse echo. With this technique, inspectors introduce sounds into a material and measure the echoes (or sound reflections) produced by imperfections on the surface of the material as they are returned to a receiver. See More
