Phased Array Ultrasonic Testing – PAUT

Phased Array Ultrasonic testing is an advanced form of Ultrasonic Testing that uses computer software to produce 3D detailed images of the material tested. Phased Array Ultrasonic Testing is used on, but not limited to, vessels, boilers, boiler tubes, and pipeline welds. This method uses multiple element probes that are controlled through the advanced software technology. This technology enhances accuracy by using a computerized process to control the parameters, spot size, focal point, angles, and focal distance. Phased Array Ultrasonic Testing is used to inspect nearly all the same materials as conventional Ultrasonic Testing. This includes fine grain carbon steel, low alloy steel, and stainless welds. It can detect flaws more accurately than conventional Ultrasonic Testing and Radiographic Testing. This method is applicable to both new construction and in-service inspections. Our personnel are trained and certified to both SNT and CGSB UT NDT Level II or III, as well as, PCN Level II.

Advantages of Phased Array Ultrasonic Testing:

  1. Advanced Accuracy
  2. Capable of testing for Creep
  3. Highly sensitive to fusion face flaws
  4. Inspects more geometries than conventional Ultrasonic Testing methods
  5. Safer and environmentally sensitive technology
  6. Can often be used in lieu of radiographic testing
  7. Equipment is portable
