A Comprehensive Comparison of Magnetic Particle Inspection Machines
Introduction Magnetic particle inspection (MPI) is a critical non-destructive testing (NDT) method used to detect surface and near-surface defects in ferromagnetic materials. With various types of MPI machines available, selecting the right one for your needs can be challenging. This guide provides a comprehensive comparison of magnetic particle inspection machines, helping you make an informed decision based on their features, advantages, and specific applications. What is Magnetic Particle Inspection? Magnetic particle inspection is a non-destructive testing method that involves magnetizing a component and applying magnetic particles to its surface. Any surface or near-surface discontinuities disrupt the magnetic field, causing the particles to gather at the defect site, making it visible for inspection. How Magnetic Particle Inspection Works The process of magnetic particle inspection includes several key steps: Magnetization: The part to be tested is magnetized using an elect...
