Magnetic Particle Examination

This NDE method is accomplished by inducing a magnetic field in a ferromagnetic material and then dusting the surface with iron particles (either dry or suspended in liquid). Surface and near-surface flaws produce magnetic poles or distort the magnetic field in such a way that the iron particles are attracted and concentrated. This produces a visible indication of defect on the surface of the material. The images below demonstrate a component before and after inspection using dry magnetic particles.

We are conducting dry/ wet, visible/ fluorescent magnetic particle examination by yoke/prod method for materials and weld joints during fabrications and in service for wide range of industries like steel plant, cement mills, nuclear power plant, petrochemical and fabrication shops.
