Phased Array Ultrasonic Testing and Time-of-Flight Diffraction are two material testing methods. This article talks about the difference between PAUT and TOFD.
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 ins...
Intertek offers a comprehensive range of non-destructive testing methods. Therefore we can provide the other methods used to complement time of flight diffraction such as phased array, in particular to perform single sided examinations of welds. ...
Time of Flight Diffraction (TOFD) In the case of a flawless weld, the relevant ultrasonic signal will consist of a so called “lateral wave”, corresponding to the direct surface path between transmitter and receiver, and a back wall echo. Between the lateral wave and the back wall echo the...

Ultrasonic non-destructive evaluation techniques, such as time-of-flight diffraction (ToFD) for which the arrival times of waves diffracted from crack tips are analysed to locate and size defects, are well understood for smooth defects. In environments where extreme changes in temperature and pressure...

Ultrasonic non-destructive testing (NDT) techniques are widely used in industry to evaluate properties of a component, material or system without causing any damage. The time of flight diffraction method (TOFD) is regarded as a valuable procedure for the detection of welding defects. We propose ...
