Magnetic Particle Inspection Flaw Detector

Magnetic particle flaw detectors utilize the principle that ferromagnetic materials produce magnetic flux leakage in a magnetic field. By applying magnetic powder or magnetic suspension, magnetic indications are formed at defect locations. They are used to detect defects such as surface and near-surface cracks in materials and are commonly employed in quality inspections of welded components and cast or forged parts.
Selection
Select AC or DC magnetization based on the magnetic properties of the material being tested; choose contact-type or coil-type equipment according to the shape of the workpiece; consider the testing environment to decide between dry or wet magnetic particle methods; determine the type of fluorescent or non-fluorescent magnetic particles based on sensitivity requirements; and match lifting force and magnetization current parameters in accordance with standard specifications.
