Ultrasonic Testing (or UT) is a method of characterizing the thickness or internal structure of a test piece through the use of high frequency sound waves.
How does UT work? High frequency sound waves are transmitted into the material. When there is a discontinuity (such as a crack) in the wave path, part of the energy will be reflected back from the flaw. We provide coupling agents in the form of paste and gels to facilitate the transmission of the ultrasonic energy into the material.
