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 yokeprod 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.
