Development of ultrasonic phassed array technology for identification weld defects and determination of their geometrical dimensions [PDF]
One of the main parameters characterizing the technical condition of the metal constructions are the presence or absence of defects such as discontinuity in welds. Critical for decision-making, here is the information about the type of defects.

PRACTICAL APPLICATIONS OF ADVANCED NDT: PAUT & ToFD
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.
