Ultrasonic Testing

Ultrasonic Testing (UT) is a NDT method of detecting internal defects in welds and materials. By emitting sound waves from the test probe and then measuring the reflection rate through the workpiece, any inconsistencies in the material, internal defects, cracks, etc. can be read on the display of the equipment.

The method requires a great deal of routine and experience from the inspector, as there are sound heads with different angles, so that internal defects that lie along the wave propagation, thus virtually do not create reflections, are nevertheless captured by examination with a different angled sound head. There will be no permanent evidence from the test and the inspector's statement/parrort will therefore be the only evidence.

Ultrasonic Testing (UT) can be used at virtually any material thickness above 8 mm, where there is room for movement of the sound head in a sufficiently large area in order to examine the full thickness of the weld or material from all necessary angles.

We also perform phased array, which you can read more about Here.
