Magnetic Particle Testing
Magnetic Particle Testing (MPT) is a non-destructive testing (NDT) method used to detect surface and near-surface discontinuities in ferromagnetic materials. It involves magnetizing the test object and applying iron-based magnetic particles, which accumulate at defect locations, making them visible under proper lighting. This technique is widely used in industries like aerospace, automotive, and construction for quality control and safety inspections.
Developers should learn MPT when working in fields involving material science, manufacturing, or safety-critical systems, as it helps ensure structural integrity and compliance with industry standards. It is particularly valuable for inspecting welds, castings, and forgings in applications where defects could lead to catastrophic failures, such as in pipelines, bridges, or aircraft components.
