Phased Array Ultrasonic Testing (PAUT) Level II

What are Ultrasonic Phased Arrays?

Ultrasonic phased arrays use a multiple element probe whereby the output pulse from each element is time delayed in such a way  so as produce constructive interference at a specific angle and a specific depth. These time delays can be incremented over a range of angles to sweep the beam over the desired angular range. For example, 40 to 75 degree beam sweep would be produced by calculating the time delays to produce constructive interference at 40, 41, 42 …75  degs. This NDT technology is also referred as Swept Beam Ultrasonic testing. The main advantages of phased array in NDE are abilities to sweep a range of angles, to display the image in real time for the swept angles, to focus.

 

Training Objectives:

Phased array ultrasonic testing course provides the knowledge required to operate equipment and perform manual & encoded phased array testing on welds. The course covers theoretical aspects on phased array application, its advantages and limitations, application of phased array. It also includes requirements of code & standards. The course also covers in depth practical aspects for application of Phased Array on welds in Pipes & Plates using required accessories such as calibration blocks, validation samples, encoders, scanners etc.

 

PAUT Level II Responsibilities:

An individual certified to PAUT Level II has demonstrated competence to perform NDT according to PAUT Testing procedures. Within the scope of the competence defined on the certificate, Level II personnel may be authorized by the employer to:

  • Select the PAUT technique for the test method to be used;
  • Define the limitations of application of the testing method;
  • Set up and verify equipment settings;
  • Interpret and evaluate results according to applicable standards, codes, specifications or procedures;
  • Prepare PAUT written instructions
  • Carry out and supervise all tasks at or below level II;
  • Report the results of PAUT
