Ultrasonic testing (UT) is a non-destructive testing (NDT) method that uses high-frequency sound waves to detect and measure flaws in materials:

A transducer sends sound waves into the material being tested. If the material is flawless, the sound waves pass through. If the sound waves hit a flaw, they bounce back and indicate the presence of a flaw.

UT can detect a variety of flaws, including cracks, laminations, shrinkage cavities, gas holes, and more.

UT can be used to measure the thickness of an object.

UT is commonly used in industrial applications on metals, plastics, composites, and ceramics.

UT typically involves an inspection system with a transducer, transmitter-receiver circuitry, and display units.
