Wet fluorescent magnetic particle testing of railway axles

Wet fluorescent magnetic particle testing of railway axles

UMPKOS-38 system is designed for magnetic particle inspection of railcar wheels axles during production and after repair.

The system is able to detect both longitudinal and transverse surface flaws (‘B’ sensitivity level as per GOST 21105) in accordance with EN 13261, GOST 31334, RD 32.144-2000, by wet fluorescent magnetic particle technique, using AC combined magnetizing (circular, polar). The system provides 100% inspection of the entire axle surface, except for ends.

This stationary-type system can be either integrated into the workshop process line or operated independently as a stand-alone MT station. Magnetic fluid is made of finely-cleaned degassed water, free from mechanical impurities and fat inclusions.

Test object specifications:

Axles with the below parameters are subject to testing by the system:

  • maximum diameter – 390 mm;
  • minimum diameter of axle journal – ... mm;
  • maximum length – 2500 mm;
  • minimum length – 1500 mm;
  • temperature of test object: +3 °С to +45 °С.
