Ultrasonic Inspection

Ultrasonic inspection uses high frequency sound waves transmitted through the material of interest. The transmitted sound wave will be reflected back to the source by both defects in the material and once the wave has reached the other side of the material. The recorded sound wave is then used to map defects in the material and also to measure the thickness of the material. The identification of defects found in a material is left up to operator experience and/or additional inspection methods. Ultrasonic inspection is costly compared with other methods requiring large equipment and operator experience.
