Teqtoflow-CG15 portable magnetic particle flaw detector is designed to detect surface and subsurface defects when testing products made of ferromagnetic materials. Incomplete fusion, cracks, and flocks can be identified.

The flaw detector is used to check the structure state, strength and other mechanical properties of various workpieces, metal structures, parts of railway transport, both at the manufacturing and during operation.

Operating principl­e: magnetization of the test object to search for various discontinuities with subsequent demagnetization.

Advantages of Teqtoflow-CG15 flaw detector

  • The low weight of the device is successfully combined with a high output current value
  • AC/DC (rectified half-wave) operating mode allows both circular and longitudinal magnetization of test objects
  • Smooth adjustment of current amplitude
  • Constant current magnetization, impulse current magnetization
  • Direct indication of the magnetizing current amplitude value
  • Flexible adjustment of impulse current, up to single pulse operation mode
  • Automatic demagnetization of test objects
  • Saving settings
  • Automatic overheating protection
  • Connecting different magnetizing devices

Objects of control:

  • Building metal structures
  • Gear wheels
  • Cast parts
  • Castings
  • Forgings

Magnetic particle inspection is a very common non-destructive testing method. A special magnetic powder is required to be applied to the surface under study.

When the control zone is magnetized the highest concentration of magnetic field lines is observed directly above the defect. Magnetized powder particles accumulate in this place and acquire a certain structure. The density of powder particles decreases when moving away from the defect (cracks, discontinuities etc.)

This is followed by a visual interpretation of the indicator lines: the localization, orientation and extent of surface and subsurface defects. The resulting pattern can also be compared with reference samples for magnetic particle inspection.
