Ultrasonic testing (UT)

Ultrasonic tests are carried out as per the standards listed below (thickness ≥ 8) and using the IBUS method (thickness range from 2 to 8 mm).
Ultrasonic testing is a volumetric testing method, which allows detecting and evaluating readings (imperfections) occurring inside the tested object. This method facilitates determining the location and scale of imperfections inside the material. It detects imperfections using ultrasonic waves, which usually have frequencies of 0.5–6 MHz. An ultrasonic head is used to emit ultrasonic waves that penetrate into the material. Discontinuities in the tested element reflect a part of the beam, which returns to the head (transducer) – reflection method. The testing technique is based on observing the impulses reflected from material discontinuities on the oscilloscope screen.
