Ultrasonic test (UT) work with the propagation of bundles of elastic waves into solid materials, that means with compression and decompression waves with frequency higher than audible sounds. Ultrasonic waves, sent into the component to be checked, are softened by the substance through which they pass, and then they are deflected or absorbed because of the breaks present in the material.
