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

The article presents the analysis of the effectiveness of acoustic feedback required in ultrasonic contact tests. The analysis included high-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 involved the use of standard specimens nos. 1 and 2 and special steel specimens having various test surfaces. The tests were performed using a normal probe emitting longitudinal waves and an angle probe emitting transverse waves.
