Magnetic particle testing is one method of non-destructive testing. It uses magnetism to detect defects.
Magnetic particle testing utilizes the phenomenon of "leakage magnetic flux" that occurs from the damaged area. By magnetizing the test specimen, the magnetic particles (or fluorescent magnetic particles) that are scattered on the surface adhere to the damaged area. By observing this, it becomes possible to detect the damage.

basic information
【Features】 - The inspection target is ferromagnetic materials, primarily iron products. - Defects are detected by applying magnetic powder to the leakage magnetic flux. - Surface and subsurface defects can be detected. 【Inspection Procedure】 - Pre-treatment (mainly removing surface contaminants) - Magnetize the inspection target. - Apply fluorescent magnetic powder (only to the defect areas). - Visually confirm the adhered fluorescent magnetic powder by irradiating with ultraviolet light. - Post-treatment (removal of magnetic powder, demagnetization, etc.)
