Phased Array Ultrasonic Testing (PAUT)

Phased Array testing is a specialized type of ultrasonic testing that uses sophisticated multi-element array transducers and powerful software to steer high frequency sound beams through the test piece and map returning echoes, producing detailed images of internal structures similar to medical ultrasound images. It is used for inspection of critical structural metals, pipeline welds, aerospace components, and similar applications where the additional information supplied by phased array inspection is valuable.

Time of Flight Diffraction (TOFD)

  • Application Such as Inspection of Piping and Pressure Vessel welds
  • Powerful Techniques because it can continuously detect and size defects
  • Location of the indication along the weld
  • Position of the indication with the respect to the scanning surface
