MPI Inspection Method, Tools, And Criteria
Magnetic particle inspection, or simply MPI inspection, is amongst the most popular non destructive tests (NDT) methods. It is important that you will realize when the inspection methods, the magnetic particle equipment used, and the standards that guide the inspection.
MPI inspection is only possible in materials that are ferro-magnetic materials like iron, cobalt, nickel, and some of their alloys like steel, which is an alloy of iron. This NDT method is used for surface as well as slightly subsurface discontinuities like voids and subsurface holes, pits, cracks, laps, and seams. The mag particle testing equipment used uses alternating current or direct current to produce a magnetic field in the test material or equipment, effectively functioning as an electromagnet. Magnetic materials such as iron oxide particles are applied on the surface getting tested. Virtually any voids, subsurface holes, pits, cracks, laps, and seams present will have small poles and there will therefore be a concentration of magnetic flux and consequently magnetic particles around them. The testing could be wet, in which case the magnetic particles are placed in carriers like oil or water and black light (UV light) used for the detection, or it could be dry, in which case powder magnetic particles are being used.
The selection of the magnetic particle equipment should be based on your particular needs. One of the most popular MPI inspection equipment is the wet horizontal MPI machine. The machine comes with a tail and head stock, which carries an inductive coil and where the portion to be tested is positioned for magnetization. The mobile power pack is a custom-built magnetizing power supply, which is popularly used to test wire wrapping. The magnetic yoke is advantageous in that it is a hand-held device. This non destructive testing equipment functions by inducing a magnetic field between 2 poles and it is common in outdoor use and in weld inspection. Only buy your non destructive testing equipment from a well-known manufacturer.
There are actually different standards in different countries and economic zones that non destructive testing equipment need to fulfil. The MPI inspection equipment or mag particle testing equipment needs to fulfil the ISO (International Organization for Standardization) standards including the ISO 3059, ISO 9934-1, ISO 9934-2, ISO 9934-3, ISO 17638, ISO 23279 in order to meet EN 1330-7, EN 1369, EN 10228-1, EN 10246-12, and EN 10246-18 European Committee for Standardization or CEN standards in the European Union. In the U.S., the non destructive tests device needs to meet the American Society of Testing and Materials or just ASTM standard, which include ASTM E1444-05, ASTM A 275 / A 275M, ASTM A456, ASTM E543, ASTM E 709, ASTM E 1316, and ASTM E 2297. Other standards that have to be fulfilled by the magnetic particle equipment are the Canadian Standards Association or CSA standards, the Society of Automotive Engineers or SAE standards in the automobile sector, and the United States Military Standard (A-A-59230) for contractors for the U.S. Military.
