ECHOGRAPH-HRP.S High-Speed UT Inspection of Bars

... for inspection of bars

At the moment, a bar diameter range from 7 to 93 mm can be tested with the ECHOGRAPH-HRP.S system. The testing system works with the immersion technique, meaning that the part of the bar to be inspected is fully immersed in water. The system uses a water chamber and several probe cassettes on which the ultrasonic probes are mounted around the circumference of the bar. No mechanical rotation is employed in this concept, therefore avoiding mechanical wear of the testing mechanics and the untested zones which might occur with helical test traces and high testing speeds.

A key feature of the testing concept with stationary probes is the high inspection speed f up to 2 m/s and the robust mechanics which shows very little wear since no rotational components are used. The ultrasonic pulse density in the transportation direction is high enough so that overlap in the transportation direction is produced. Therefore, another important feature of the system is the detection of short defects.
