Magnet Particle Test in Detail

Magnet Particle Testing (MPT), also known as Magnetic Particle Inspection (MPI), is an effective non-destructive testing technique used to reveal surface and slightly subsurface discontinuities in ferromagnetic materials. By magnetizing the test object and applying magnetic particles, discontinuities such as cracks, seams, and inclusions become visible through the distortion of the magnetic field.

At 2R Inspection, we perform both dry and wet MPT methods using visible or fluorescent particles, tailored to specific materials and conditions. Our certified inspectors follow international standards such as ASTM E709 and ISO 9934 to ensure precision, repeatability, and traceable documentation. MPT is commonly used on welds, shafts, gears, and heavy structural parts in critical applications. Whether it’s for in-service inspection, quality control during manufacturing, or acceptance testing after repair, our MPT services provide fast, reliable results with minimal disruption to operations. With 2R Inspection, you can trust your components are safe, compliant, and ready for demanding use.
