About

ToFD is an innovation of ultrasonic testing which uses two probes. One probe sends the ultrasound and the other one is used as a receiver. Instead of recording the ultrasound that is reflected by defects, it detects diffraction of sound waves that emanate from the tips of a defect. ToFD inspection provides accurate information about the length and height of defects. Unlike other testing methods, ToFD can detect flaws regardless of their orientation. 

ToFD inspection is used for the inspection of welded joints, but it is also extremely suitable for the inspection of forgings, ship hulls, pressure vessels, carriage decks and steel structures. The use of this method is fast and extremely accurate, which has resulted in an increase in its popularity in recent years.
