Phased Array

A Phased Array System is based around a specialized ultrasonic transducer that contains many individual elements that can be pulsed separately in a programmed pattern. An array transducer contains a number of separate elements in a single housing, and phasing refers to how those elements are sequentially pulsed. Benefits of Phased Array over conventional UT:

  • Beam steering, commonly referred to sectorial scanning, can be used for mapping components at appropriate angles.
  • The ability to test welds with multiple angles from a single probe greatly increases the probability of detection of anomalies.
  • Electronic focusing permits optimizing the beam shape and size at the expected defect location.
