ULTRASONIC TESTING EQUIPMENT Principle When ultrasonic waves from a piezo-electric crystal are made to propagate in a material through proper coupling it will be partially reflected or refracted when there is a change in medium or an interface, say the presence of a discontinuity or the opposite surface of the sound entry. • Ultrasonic testing is completely safe method of NDT and it is extensively used in many basic manufacturing and service industries. Flag for inappropriate content. • Ultrasonic examinations can be conducted on a wide variety of material forms including castings, forgings, welds, and composites. Multiple advances in ultrasonic non-destructive testing have taken place in recent times, evolving from application to conventional thickness to the use of more advanced methods encompassing various modes. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials.
