For manufacturers and inspectors working with critical metal components, quality assurance is non-negotiable. When even the smallest defect can lead to system failure, robust non-destructive testing (NDT) becomes an essential part of the process.
Among the most trusted NDT methods is Magnetic Particle Inspection (MPI), a technique widely adopted across industries to detect surface and near-surface flaws in ferromagnetic materials. DCM Tech, Inc. is known for delivering dependable, high-performance inspection equipment tailored to the demands of industrial-scale operations.
What Is Magnetic Particle Inspection (MPI)?
MPI is a powerful non-destructive method for identifying discontinuities in ferromagnetic metals like steel, iron, and nickel-based alloys. The process works by magnetizing the component and applying magnetic particles to its surface. Any disruptions in the magnetic field—caused by cracks or void-attracting the particles, making flaws visible to the inspector under UV light.
This technique is fast, repeatable, and effective, especially for detecting fine cracks that are difficult to identify using other methods.
