NDT-Inspect started the discussion Lateral wave removal ToFD in the forum Time of Flight Diffraction 2 years ago
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…

Time of Flight Diffraction (ToFD) 2 years agoTo calculate the size and location of defects in a weld using ToFD, the following steps are typically performed:
- The distance between the transducers (d) and the angle of incidence (θ) are measured.
- The time it takes for the ultrasonic pulse to travel between the transducers and reflect off a flaw is measured (t).
- The velocity of the ultrasonic…

Time of Flight Diffraction (ToFD) 2 years agoToFD (Time of Flight Diffraction) is a type of non-destructive testing (NDT) that is used to detect and size defects in welds. 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…

Time of Flight Diffraction (ToFD) 2 years agoToFD, or time-of-flight diffraction, is a type of ultrasonic testing method used to detect and evaluate defects in materials. 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…

Yep. I guess it was a leak if in service pipe/ weld.
