Magnetic Particle Testing

Magnetic Particle Inspection is used to identify surface and near surface discontinuities in ferromagnetic materials such as steel and iron. The Technique uses the principle that magnetic lines of force (flux) will be distorted by the presence of a discontinuity. Discontinuities (for example, cracks) are located from the flux distortion following the application of fine magnetic particles to the area under test.


  • MPI crack detection for automobile components using Head shot and Coil shot.

  • MPI crack detection for automobile components using Head shot and Coil shot. Bench type unit with maximum current rating 2000 Amperes and 5000 Amperes meets the requirements of ASTM E709 and ASTM E1444

  • Portable Prod Equipments upto 1500 Amperes are used for testing of raw materials and welds.

  • MPI available with visible wet particles and Fluorescent wet particles

  • The concentrations of the particles are controlled by settling test with the values for visible particles 1.2ml to 2.4ml and for Fluorescent bath 0.1mL to 0.4mL.

  • Electromagnetic yokes are available for testing of welds at site locations. To ensure safe working at location that are 'intrinsically safe' battery operated electromagnetic yokes are used.

  • All MPI procedures are approved by ASNT NDT Level 3

  • Calibrated black light units (UV-A light) are used for all types of fluorescent magnetic particle examinations

  • UT jobs are carried out using procedures approved by ASNT NDT Level 3
