Component tested
The application chosen for this industrial version is the testing of bottom head penetration tubes which is an elaborate process involving as many as four NDT techniques: Ultrasonics (UT) Shear Waves 45°, Longitudinal Waves 0°, TOFD, and Eddy Current (EC).
Features
First the native formats used for the controls are converted into a single-multitechnique format (TRAPPIST) which can be stored in and retrieved from the system database.The PACE UT and EC analysis tools include interactive 2D and 3D visualization, advanced processing and data registration features meeting the requirements of a control procedure. Thanks to the database, traceability is maintained throughout the data analysis process.
The analysed data is then stored in terms of potential indications, seriousness, extension and position. This symbolic information, available for all NDT techniques, is then automatically correlated using a rule based system whose rules originate from the procedure itself in order to produce a diagnostic.
First results
The first field tests performed with a pre-industrial prototype of PACE indicate a significant increase in productivity (for instance the symbolic correlation processing time has plummeted from several days to several minutes). These results validate on an industrial application the fundamentals of the PACE system.
