Magnaflux Devices - Advice on choosing the best product

Different engineering methods are for sale to find surface disorders and subsurface discontinuities in metals. One of the most popular NDT calibration (Low Destructive Testing) methods is called “Magnaflux�ing, also known as MPI (Permanent magnet Particle Inspection). Using this method works by creating a permanent magnetic field on the area to be inspected. Which means, it can work on almost all ferromagnetic materials like flat iron, nickel and many other metals. A typical Magnaflux process involves these steps: - First, the material is to be magnetized. This can be done by 50 percent ways:Either way, a magnetic field is defined on the surface to be analyzed Direct Magnetization by delivering electric current through the steel surface Indirect Magnetization by simply creating a magnetic discipline from another origin other than the metallic surface - When a metal surface carries a magnetic field placed on it, the permanent magnet lines of force will be running parallel to the surface - If the surface does not have any defects, these magnetic force lines will likely be running continuously with no disturbance - When there is a defect from the surface or subsurface amount, it means, air will probably be present in that region instead of metal. Air can’t support same amount of magnet field as metallic, this will cause disturbances from the magnetic force traces, which are known as permanent magnetic flux leakage - MPI as well as Magnaflux devices can discover this magnetic flux leakage and find out the area wherever surface defects are present. Handheld devices including Magnetic inspection yokes bring easy outdoor inspections of metal surfaces - Now, magnet powders (small particles) are applied in the surface - They will be immediately attracted to the area in which magnetic flux leakage occurs. This can be used to find the faulty zone and is notable by the technician appropriately! - While examining a surface utilizing Magnaflux technology, it is recommended that the surface is tested in 2 angles that are 90 degrees aside (horizontal and vertical). This helps to locate the defect region accurately
