In ToFD (Time of Flight Diffraction), lateral wave removal is a technique used to eliminate or reduce the effects of lateral waves on the ultrasonic signals used to detect and size defects in materials. Lateral waves are waves that travel parallel to the surface of the material being tested, and can interfere with the measurements and…

  1. The distance between the transducers (d) and the angle of incidence (θ) are measured.
  2. The time it takes for the ultrasonic pulse to travel between the transducers and reflect off a flaw is measured (t).
  3. The velocity of the ultrasonic…

ToFD uses ultrasonic waves to inspect the weld and determine the presence and size of any defects, without causing any damage to the material.

ToFD is based on the principle of time of flight diffraction, which states…

ToFD is an advanced form of ultrasonic testing that uses multiple transducers to generate and receive ultrasonic waves.

The time it takes for the ultrasonic waves to travel from the transmitting transducer to the…
