A new synthetic training environment system based on an ICT-approach for manual ultrasonic testing

• We developed an innovative synthetic NDT training environment system.
• The system is implemented with a dead-reckoning based positioning unit.
• The optical positioning unit has been tested with very high accuracy.
• Test bed trials with the developed system revealed 100% PoD from the trainees.

Training to qualify as a manual ultrasonic inspector takes a long time and costs a considerable amount of money. We developed a virtual training environment using an innovative dead-reckoning optical sensor that yields translational position which offers additional information to operators and examiners alike. The training environment contains a library of test scenarios, shows surface coverage, measures the time of inspection, indicates detected defects and provides a performance score. Our test-bed trial results using a pool of Ultrasonic Test (UT) qualified and unqualified participants on two virtual training blocks that contain 2 flaws each reveal 100% detection and an accuracy of 5 mm in locating defects in more than 50% of the measured defect locations.
