It is a technique of control based on the reflection and the diffraction
that the acoustic waves feels inside of a material, when these meets
an obstacle that prevents its propagation.
It is employed in the control of weldings, fusions, forged, compact
and fine grain sheets.
The ultrasounds are also used in the measurement of thicknesses of materials.
Inside of DUEMME, with the aid of paricular equipments, the production
of centrifuged tubes of an important national company is totally controlled.
