What is the Goel UT Challenge ?

Structural ultrasonic testing (UT) comes with a multitude of challenges. For example gathering and interpreting indications from the backing bar, varying gaps, mismatch, gaps between faying surfaces, areas of limited access due to bolt holes and other geometrical features and many more. At AEIS, we recognize the level of skill that it takes to navigate the complexities encountered in UT. The Goel UT challenge has been created to do just that, recognize the best structural UT technician.

Although we are a one-stop solution for inspection and testing needs, AEIS specializes in welding and non-destructive testing (NDT) on large infrastructure. In particular, standard and advanced UT techniques such as Phased Array UT for structural applications. We are excited to share our passion for UT with fellow technicians and industry leaders.

Who Can Participate?

Participants must be a UT Level II (SNT-TC-1A/ISO 9712), with at least two years of experience. Participants cannot be employees of AEIS.

Competition Structure

The UT challenge has two rounds. The first round of up to 56 participants will take place on Friday, December 3rd. Six candidates will then advance to the second round held on Saturday, December 4th.

Scoring Methodology

  • An indica­tion will be considered a "detected flaw" if at least two of the following attributes are correctly identified within the listed tolerances:(1) Indication Rating within ±6 dB
    (2) Indication Length within +1 in. to -0.5 in
    (3) Indication Depth within ±0.25 in.
  • An indication will be considered a "false indication" if the flaw does not exist, but is reported. The rate of flaws detected, based upon reporting of the flaw and its location is: D = detected flaws/total flaws.
  • The rate of false indications is: F = false indications/total indications. The UT technician rating is: R= 1/2(1 + D - F).
  • To qualify for the second round of the competition, the participant needs to achieve all of the following: (1) An overall rating R of 0.90 or higher
    (2) A detection rating D of 0.87 or higher
    (3) A false indication rating F of 0.15 or less
  • If more than six candidates meet the above criteria, the six technicians with the highest overall R rating will be selected to advance to the second round.
  • The winner of the second round will be based on the highest overall R rating. In the event of a tie, the accuracy of the dB rating, followed by length and depth will determine the winner.

Participants are required to bring the following equipment

  • UT flaw detectors
  • Transducers
  • Cables
  • Calibration block and a calculator.
  • Couplant (Magnaflux Sonotrace Gr 30)
  • Rags, pencils and worksheets
  • Accept-reject criteria tables will be available at each test station.
  • Participants are advised to calibrate their Flaw Detectors in advance with their set of transducers, cables and calibration block
  • Test piece thicknesses can be 3/8", 1/2", 3/4", 1", 1-1/4" and 1-1/2"
