On October 1-4, 2023 OKOndt GROUP attended Railway Interchange 2023 - the largest North American railway event. This time the exhibition took place in Indianapolis, Indiana, USA (Indiana Convention Center) and brought together over 700 exhibitors and more than 8, 000 visitors who are the major influencers in the industry. Thank you to everyone who was with us at the RI 2023!

 It is intended for determination of main parameters of ultrasonic welded joints testing carried out by various ultrasonic flaw detectors. The article provides the information on the main technical specifications and KОU-2М application areas.KОU-2М set of calibration blocks according to GOST 14782-86 It is intended for determination of main parameters of ultrasonic welded joints testing carried out by various ultrasonic flaw detectors.

KОU-2М set of calibration blocks

 It allows to perform:

  1. Selection and comparison of angle beam probes by ultrasonic waves frequency with the error of ±10% in the range of 1,25-5 МHz.
  2. Measurement of probe angle with the error of ±1°.
  3. Determination of ultrasonic beam emergent point position with the error of ±0,5 mm.
  4. Evaluation of dead area size.
  5. Check of depth gauge operation accuracy of flaw detector with the error of ±10% by SО1 and ±8% by SО2.
  6. Evaluation of equivalent defect area.
  7. Evaluation of beam resolution of flaw detector when operating straight beam and angle beam probes.
  8. Evaluation of wedge angle of angle beam probe with the error of ±2,5°.
  9. Determination of conditional sensitivity and equipment setup for the given calculated value of ultimate sensitivity with the error of ±1 mm.
