Ultrasonic Flaw Detection

Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. Ultrasonic testing is most commonly performed on steel (pipes) and other metals and alloys to identify subsurface defects in welds. It can also be used on concrete, wood and composites, but with less resolution. It is used in many industries including steel and aluminium construction, metallurgy, manufacturing, aerospace, automotive and other transportation sector.
