Magnetic particle inspection is a simple but sensitive method for detecting irregularities in the surface of ferromagnetic materials with a relative permeability µr >100, e.g. steel, cast iron, cobalt, nickel. Inhomogeneities close to the surface can also be detected. The depth of detectable indications depends on the field used:

Field max. depth of indication
Alternating field 1 mm - 2 mm
DC field 2 mm - 3 mm

Surface crack inspection with the fluorescent magnetic particle testing - the crack indication is clearly visible under UV irradiation

Weld seam testing with the magnetic particle testing with coloured (here black) suspension and white background colour (black-white method)

During magnetisation of the ferromagnetic material, leak fluxes occur over material separations (e.g. cracks, pores). The detection can be performed as follows:

with a flux leakage probe
by the ferromagnetic particles in the magnetic powder suspension.
These are attracted by the flux leakage and congregate above the material defect.

 
HELLING offers various aerosol detection media (fluorescent or coloured) in the form of

  • Dry powder
  • Liquid water-based concentrate
  • Ready-to-use oil-based suspension

MT detection media for magnetic particle testing (aerosols) - fluorescent or coloured suspensions based on water or oil

White background colour to improve contrast and cleaner for pre- and final cleaning

HELLING develops test facilities like

  • Hand yoke magnets
  • Cross yokes
  • Permanent magnets

to generate the magnetic field. These are manufactured at HELLING and can thus be optimally adapted to the customer's test conditions.

Hand-held yoke magnet for magnetisation, e.g. for non-destructive testing of a weld seam with magnetic particle testing

Test bodies and reference blocks according to international standards enable the detection media to be checked in accordance with the standards.

Reference blocks for magnetic particle testing to check the indication sensitivity of the detection media (magnetic particle suspension)

Furthermore, HELLING manufactures fully equipped testing systems for magnetic particle testing according to customer-specific requirements. This includes for example

  • Crack testing benches of different sizes
  • Railway wheelset testing facilities
  • Test tables for testing cylindrical, rectangular or irregularly shaped test specimens
  • Test benches for serial testing
  • Test benches for training purposes

Wheelset testing system ROD-A-MAT for combined testing of wheelset axle and wheelset wheels with fluorescent magnetic particle testing
