Ultra sound testing

Non-Destructive Testing

The check by the ultrasound (UT ultrasonic test) uses the propagation inside the solids of elastic waves, with a frequency higher than the frequency humanly audible, that sent to the component to be examined are lessened by the matter that reflects, diverts or absorb them due to the discontinuity in the material.
To sum it up this method allows the identification of internal defects that cause the reflection, the deviation or the absorption of an ultrasound bundle distant from transducer from a few mm to different meters.

Therefore if we exclude the defect visible easily, whose signal leaves no doubt, in most cases and especially in the more particular cases, aimed to the identification of little defects, the signal interpretation requires a wide preparation and experience and maybe a n additional comparison with others methods. For these reason Punto Netto constantly trains its workers. These workers, having also a strong knowledge of CND methods, are the best choice to rely on for this check. Also in this case Punto Netto has got the best products for this inspection and the mobile equipment to perform the activities at plant, to avoid cost due to the handling of goods.
