In 2020, researchers introduced the novel concept of in-process calibration applied to ultrasonic NDT. This approach centers on manufacturing a second duplicate sample containing intentionally embedded tungsten inclusions, processed with identical parameters as the main production sample. Both samples are then inspected using a high-temperature robotic NDT process, allowing direct comparative measurements between the real part and the calibration sample. The study demonstrated that in-process weld defect detection using this calibration technique could more reliably identify defects that would otherwise pass acceptance tests using traditional calibration methods. This innovation significantly improved the reliability of ultrasonic testing for critical applications.
