Magnetic Particle Inspection (MPI) MAGNETIC PARTICLE INSPECTION Magnetic Particle Inspection (MPI) is an NDT method that can use magnetism to detect surface and subsurface discontinuities in ferromagnetic materials. MPI is generally used to determine parts fitness for use. It is a relatively easy and quick method that is widely used in various sectors such as automotive, oil and gas, aerospace,      petroleum,                   power generation, etc. This method detects surface or subsurface discontinuities such as cracks, porosity, laps, seams, inclusions in ferromagnetic materials. One of the major advantages of this method is, it is a relatively fast method and gives an immediate indication on the surface. This method works by inducing the magnetic flux in the part to be tested. If any discontinuities or detect is present on the surface or near the surface the magnetic field distorts and leaks around the defect. By application of magnetic medium on the surface, the particles attract the area where flux leakage has occurred producing a visible indication of the defect. This indication can be evaluated by the operator any necessary measures are taken if any.

Magnetic Particle Inspection (MPI) is a Non-Destructive Testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferroelectric materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current which may be either Alternating Current (AC) or some form of Direct Current (DC) (rectified AC). The presence of a surface or subsurface discontinuity in the material allows the magnetic flux to leak, since air cannot support as much magnetic field per unit volume as metals. Ferrous iron particles are then applied to the part. The particles may be dry or in a wet suspension. If an area of flux leakage is present the particles will be attracted to this area. The particles will build up at the area of leakage and form what is known as an indication. The indication can then be evaluated to determine what it is, what may have caused it, and what action should be taken, if any. This examination should apply in a row stage and final stage. Process mostly used for bar stage,forging casting and after heat treatment process .

MAGNETIC PARTICLE INSPECTION For Detection of Surface and Subsurface cracks Magnetic particle inspection is often carried out to help determine an item’s fitness for use or conformity. This quick and relatively easy to apply technique is widely used in all industry sectors including aerospace, automotive, petrochemical, structural steel, and power generation to inspect a variety of products and equipment such as engine, suspension and braking system components, castings, forgings and weldments etc.

MT detects surface and near-surface imperfections such as cracks, seams and laps in ferromagnetic materials, and is used to assess location, size, shape and extent of these imperfec- tions. When the test object is magnetized, flaws perpendicular to the magnetic field direction cause f lux leakage. Magnetic particles applied to the surface are held at the location of the imperfection by flux leakage.

This process used for detecting surface and slightly subsurface discontinuities in ferroelectric materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The reason we use this test is to find small defects in objects before they become bigger defects and cause serious problems. In magnetic particle inspection, a magnet or electrical current is used to establish a magnetic field in the object. Iron filings are then dusted on to the surface of the object. The filings should align along the magnetic lines of force. If a crack or other defect is present, the magnetic lines of force will be disrupted and the magnetic particles will cluster along the edges of the flaw.

Mt (magnetic particle testing) it is a non-destructive testing (ndt) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source. Dry particle inspection in this magnetic particle testing technique, dry particles are dusted onto the surface of the test object as the item is magnetized. Dry particle inspection is well suited for the inspections conducted on rough surfaces. When an electromagnetic yoke is used, the ac or half wave dc current creates a pulsating magnetic field that provides mobility to the powder. The primary applications for dry powders are unground welds and rough as-cast surfaces. Dry particle inspection is also used to detect shallow subsurface cracks. Dry particles with half wave dc is the best approach when inspecting for lack of root penetration in welds of thin materials. Half wave dc with prods and dry particles is commonly used when inspecting large castings for hot tears and cracks. Wet suspension inspection wet suspension magnetic particle inspection, more commonly known as wet magnetic particle inspection, involves applying the particles while they are suspended in a liquid carrier. Wet magnetic particle inspection is most commonly performed using a stationary, wet, horizontal inspection unit but suspensions are also available in spray cans for use with an electromagnetic yoke.

Magnetic particle testing is a method for detecting cracks and other discontinuities on surface and subsurface of Ferro-magnetic materials. Sensitivity of detection is maximum at the surface and diminishes rapidly with increasing depth of sub-surface defects. Detection of defects depend on the fact that when a material is magnetized, discontinuities which lie transverse to the direction of magnetization cause distortion of the magnetic lines of flux and a leakage field is formed at or above the surface, some of these particles are held by the leakage flux. These magnetically held collection of particles form outline of effects and show location, shape and extent of the discontinuities. A number of factors such as direction and strength of the magnetic field, magnetic character of the part, location and orientation of discontinuities and type of the magnetic powder applied, affect the formation of the powder pattern, and therefore exact location of the flaw is indicated by the method.

This method is used for the detection of surface and near-surface flaws in ferromagnetic materials and is primarily used for crack detection. The specimen is magnetised either locally or overall, and if the material is sound the magnetic flux is predominantly inside the material. If, however, there is a surface-breaking flaw, the magnetic field is distorted, causing local magnetic flux leakage around the flaw. This leakage flux is displayed by covering the surface with very fine iron particles applied either dry or suspended in a liquid. The particles accumulate at the regions of flux leakage, producing a build-up which can be seen visually even when the crack opening is very narrow. Thus, a crack is indicated as a line of iron powder particles on the surface. The method is applicable to all metals which can be strongly magnetised – ferritic steels and irons, but not generally austenitic steels. The method of magnetisation must produce a magnetic field with lines of force at a large angle to the expected direction of the cracks to be detected, so that it is usual to apply the magnetisation more than once in different directions, for example in two directions mutually at right-angles, but methods of swinging the field direction during magnetisation are available.

Magnetic particle Inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current, which may be either alternating current (AC) or some form of direct current (DC) (rectified AC).

We are providing magnetic particle testing services. We are magnetizing the inspection job and applying magnetic particle (dry or wet magnetic particle)on surface of the part. Then we will get the indication on the job surface (indication -> particle accumulation) due to the magnetic flux leakage. Using this visible indication we can identify the type of defects in the material. This ndt method is called as “magnetic particle testing”
