Detection process
The gantry structure is adopted and combined with the ultrasonic water film method to perform ultrasonic detection of the rim tread. The rim is input into the flaw detector from the track below, the probe holder drops, and the rim leaves the flaw detector after rotates one circle.
Detection standards
EN 12668-2 《Non-destructive testing-characteristics and certification of ultrasonic inspection equipment》
GB/T10061-1999《General technical requirements for A-type pulse reflection ultrasonic flaw detector》

The form of mechanical structure
It adopts gantry type and matches the ground track. The probe holder can move freely left and right to adapt to rims with different gauges.
Technical key points
The flaw detector is digitalized, modularized, with strong interchangeability and scalability, which is convenient for maintenance;
—The flaw detector has high technical indicators and meets national and European standards;
—The components of the system are of military grade, with high stability, anti-interference and reliability, excellent signal-to-noise ratio, and strong ability to find defects;
—All data of the system can be saved, recalled, and output, which is convenient for later traceability;
—The system contains a flaw detection expert system, which can calibrate the equipment on schedule, and then enter the normal working mode after calibration;
—The system is fully automated, without manual intervention.
