PRACTICAL APPLICATIONS OF ADVANCED NDT: PAUT & ToFD
, 2019 Phased Array Ultrasonic Testing • Phased array consists of a number of ultrasonic elements arranged in a single probe (transducer), each of which can be pulsed independently. Time of Flight Diffraction • It is based on diffraction of ultrasonic waves on tips of discontinuities, instead of geometrical reflection on the interface of the discontinuities.
