What is ultrasonic testing?

Ultrasonic testing (UT) is a non-destructive testing (NDT) method that uses high-frequency sound waves to detect defects, measure thickness, and evaluate the properties of materials. It is commonly used in industries such as manufacturing, aerospace, and oil and gas to inspect welds, structures, and components without causing any damage. UT can identify internal flaws, such as cracks or voids, that may not be visible on the surface. Trained technicians use specialized equipment to transmit and receive ultrasonic waves, analyzing the reflected signals to assess the integrity of the material.
