Magnetic Flux Leakage Testing (MFLT)

MAGNETIC FLUX LEAKAGE TESTING (MFLT)

AC current flows through two rotating magnetizing yokes. The yokes magnetize the test piece at a distance of a few millimeters. Special test shoes with protected probes located between the yoke arms scan the surface of the test piece by sliding over it.

The AC magnetic field generates a magnetic flux inside the test piece. If the test piece has an inconsistency in its surface, the magnetic field is deviated and a leakage flux is generated. The sliding probes detect the leakage flux and the NOVAFLUX® testing system displays and reports this deviation including exact localization information.
Few advantages are :

  • Defects as small as 0.1 mm can be detected.
  • Highly sensitive test method for the detection of longitudinal defects on black steel bars.
  • No coupling liquid required.
  • Reliable and reproducable test results.
