Time-of-Flight Diffraction (ToFD)

Time-of-Flight Diffraction Ultrasonic Testing is among the most modern testing methods for the detection of imperfections and defects in materials. Conventional Ultrasonic Testing uses sound reflection. ToFD testing measures the time-of-flight of an ultrasonic pulse to determine the position of a reflector. The application of this method is fast and extremely accurate. This has resulted in an increasing popularity over the last few years.

During the ToFD testing no ionising radiation is emitted. The equipment is portable and easy in operate, so our technicians can perform ToFD testing at any place and anytime, without disturbing production activities.

ToFD testing is widely applicable, and MME Group often uses this method in combination with other testing methods. The method is mostly applied to examine welds, but can also be used for the inspection of forgings, hulls, vessels, deck spaces and steel constructions.
