Magnetic Particle Testing in Chennai

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. Our techniques for magnetic particle inspection include: · Yoke · Bench (for headshot direct induction) · Coil shot · Prods · Central conductor ALPHA SONIX has skilled NDT personnel that have gained years of experience in performing MPI and are Level 2 and 3 qualified with ASNT. We provide the testing both on-site at our customers’ premises. When selecting ALPHA SONIX for your magnetic particle inspection (MPI) needs, you have an assurance that your maintenance schedules will be met and you will benefit from the expertise that our inspectors provide. Our reports will provide you with the necessary data to take preventive measures and will help in the management of assets.

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.

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”
