Evaluation of the Effectiveness of Low-Density Couplants in Ultrasonic Tests

Ryszard Krawczyk

The article presents the analysis of the effectiveness of acoustic feedback required in ultrasonic contact tests. The analysis included low-density couplants, the use of which aimed to provide the most effective transfer of the beam of ultrasonic waves from the probe to an element subjected to an ultrasonic test. The tests were performed using a normal probe emitting longitudinal waves and an angle probe emitting shear waves. The tests involved the use of standard specimens as well as steel specimens having various test surfaces.
