Magnetic Particle Testing Services - High Sensitivity Flaw Detection | Permanent And Electromagnet Applications, Fine Magnetic Particle Visibility

We offer our customers a wide range of Magnetic Particle Testing Services. In order to apply a magnetic field to the specimen, a permanent magnet, electromagnet, flexible cables and hand-held prods are used. If the material is sound, it allows the concentration of the magnetic flux below its surface. If the material is flawed, the flux interacts with the magnetic field and is locally distorted. After leaking from the surface, this flux accumulates in the region of the flaw. When the fine magnetic particles are attracted to the flux leakage area and are applied to the surface of the specimen can create a visible indication of flaw. This process cannot detect the deeper subsurface flaws, because of the influence created by the distorted lines on the magnetic particles, which become weaker with distance. The increase in the depth of flaw can result in the rapid fall of sensitivity. Black iron particles and yellow or red iron oxides are commonly used material for this process. Our Magnetic Particle Testing Services are available at most competitive price.
