Test Bench for Wheelsets (Disassembled Condition)
ECHOGRAPH WHEELSET V

The complex automatic test bench ECHOGRAPH WHEELSET V was developed for the inspection of wheel rims and axles of different types. With ultrasonic and eddy current probes, the wheel rims are tested for longitudinal, transverse and volumetric defects. The wheel is inspected with six phased array probes simultaneously and fully automated after the wheelset data is entered. The probe holders automatically move into position at the wheel rims of the wheelsets. Testing is done on the wheel rim as well as on the front face of the flange. The wheelset is turned automatically during this process. The ECHOGRAPH WHEELSET V is able to detect indications from a depth of 1 mm. After successful testing, the wheelset is automatically rejected from the wheel spinning stand. The test results are presented as bar
diagrams with A-scans connected for every probe. The inspection of the axles is done via C-scan. Functions such as hiding form indications (without affecting the flaw indication) and zooming selected areas including their A-scans facilitate the work of the testing personnel. Recorded data is saved, logged and made available to higher-level systems via a database.
