We have improved the CUD-type flaw detector for testing in the railway maintenance sector. Work carried out with a universal device is tedious and involves wasting time on unnecessary activities. Therefore, based on our experience, we have improved its operation and added software to support the operator. Thanks to this, the CUD-type flaw detector can be successfully used as the basis for a semi-automatic stand or as a classic handheld flaw detector. Of course, it also allows for testing other materials, e.g. welded joints. The CUD-type flaw detector has a dedicated program for testing axles and wheel rims, guiding the operator step by step through the testing process and enabling automatic report generation.
The unique features of the CUD flaw detector include:
colour touch screen,
four independent channels,
two independent markers (gates),
battery life – up to 28 hours,
the possibility of implementing dedicated software guiding the operator through the testing process and automatic report generation,
WiFi communication with a computer,
automatic evaluation of defect size according to DAC and DGS (AVG),
catalogs of probes, materials and flaw detector settings,
automatic time base,
ease of use,
bright screen visible also in full sunlight and from any angle,
24-month warranty.
Ultrasonic testing of axles and wheel rims during operation is performed using the comparative method – any indications on the tested axle are compared with the indications obtained in the same place from artificial defects made on the reference axle. Each type of axle (changing one dimension generates a new type) should have its own axle standard. Calibration on the reference axle is performed at the beginning of each shift. During the test, the operator should have easy access to the reference of the tested axle at all times. We offer the execution and certification of reference cuts on axles provided by the Purchaser. We also offer axle testing instructions. Both the standards and the instructions are approved by a person with a level 3 certificate in the railway maintenance sector in accordance with EN ISO 9712. The surfaces of the application of the inclined probes are the front side of the journals (testing the axle without disassembly) or the side surfaces of the journals and the central part (testing the disassembled axles). Axles and wheel rims are tested with normal probes during production. Artificial defects on the standards are flat-bottomed holes. The CUD flaw detector is the only one on the market that has a dedicated program that guides the operator step by step through the testing process. All calibration settings and data on the tested wheelsets are remembered. Thanks to this, at each step of the test, the actions that the operator should perform are indicated and the appropriate settings are recalled. In the event of an unacceptable indication, its position and a screenshot (ScanA) are saved. Finally, a report is automatically generated according to the established template.
