MAGNETIC PARTICLE TESTING

Non-destructive testing (NDT) is a method industries use to check materials or structures for differences, welding issues, or flaws without causing harm to the original part. It's also called non-destructive examination (NDE), non-destructive inspection (NDI), and non-destructive evaluation (NDE). The goal is to ensure the quality of materials and structures without damaging them during the testing process.

One of the Major method is Magnetic Particle Testing

Magnetic particle testing relies on the phenomenon known as magnetic flux leakage, which occurs within a ferromagnetic test object in the presence of a discontinuity. This phenomenon involves the interaction of magnetic field lines with any disruptions or irregularities in a component. When a ferromagnetic material experiences a flaw or defect, the magnetic field lines are affected, resulting in detectable flux leakage. This interaction forms the basis of magnetic particle testing, where the identification and examination of these magnetic flux variations provide insights into the presence and characteristics of discontinuities within the tested material.
