Non-Destructive Testing

Ultrasonic Testing (UT)Level 3

We deploy advanced ultrasonic technology to inspect critical components and detect internal defects that would be invisible to other testing methods.

High-frequency sound waves penetrate the material and reveal discontinuities inside it — from cracks and inclusions to delamination at the interface of bonded materials, such as the white metal overlay in plain bearings.

✓ Accredited by E.SY.D. — Cert. No. 134 for Testing
