Magnetic particle testing method detects surface and subsurface discontinuities. The depth of detection varies considerably from material to material. It is based on magnetic permeability, strength of magnetic flux generated, magnetic particle properties, sensitivity desired and orientation of discontinuity.
Although test method can prove sensitivity up to 14mm under ideal conditions, but in actual practice the sensitivity is much lesser. Our MPI training facility is serving candidates from Hosur, Mysore, Mangalore, Delhi, Hyderabad, Patna, Cochin and Ahmedabad apart from lot many other cities in India.
MPI inspection method is used for testing Automobile components, railway components, engineering components, shafts, gears, forgings, castings, plates, bars, rods, rolled products. It is also applicable for cylinders, pistons, hydraulic components, pressure vessel and boiler components, welded joints, Aerospace components, mining, oil and gas pipe line construction, storage tanks, bridges etc.
Also this method detects fatigue cracks during in-service discontinuities effectively. MPI equipment such as Permanent magnets, yokes, bench type with head shot technique, central conductor and coil prod technique are common. MPI testing method also can be suitable for automation to test mass production components for detecting cracks and other anomalies.
