Ultrasonic Testing

Ultrasonic Testing (UT) uses high frequency ultrasonic waves to detect surface breaking and internal imperfections, measure material thickness and determine acceptance or rejection of a test object based on a reference code or standard.

In simple terms, an ultrasound transducer is moved over the material being inspected, emitting pulsed waves of high frequency sound which travel through the subject matter and return to the transducer or a separate receiving device. Changes in the amount of sound received reveals imperfections in the subject material.
