Ultrasonic testing is a high technology non-destructive method of testing that is applied to test internal defects, discontinuities and thickness differences in metals. This method is capable of detecting flaws accurately, as it does not damage the component by transmitting high-frequency ultrasonic waves. Quality assurance of industries like the aerospace, power plants, construction, manufacturing, and oil and gas industries requires ultrasonic testing. It is safer, more reliable, and facilitates adherence to international standards of NDT, while also reducing inspection downtimes.
