Ultrasonic testing (UT)

In ultrasonic testing, W.S. Werkstoff Service examines components non-destructively using high-frequency sound waves. A probe transmits ultrasonic pulses into the material, where they propagate at a sound velocity determined by the material. When the waves encounter interfaces, cracks, shrinkage cavities or other irregularities, they are reflected and detected by the testing instrument. The transit time, signal strength and position of the indications provide information about internal defects and wall thicknesses. The appropriate frequency is selected according to the material, component thickness and testing task. Finally, the measurement results are evaluated and documented in accordance with the applicable standards.
