Ultrasonic Testing (UT)
Ultrasonic testing is one of the core methods within the broad spectrum in the non-destructive testing industry. It allows the characterization of the internal structure of a component using high frequency sound waves, without impacting its serviceability, providing instantaneous results.
Ultrasonic Testing (UT) is based on the propagation of acoustic waves. Acoustic waves are mechanical vibrations passing through solid, liquid, or gas. Such waves may be reflected or refracted at interfaces. An interface is a change in medium-for example, metal versus a nonmetallic inclusion or void.
