Industry & Occupation
Classification
Summary
An inspection technician who uses magnetism to detect defects on the surface and subsurface of metal parts and welds.
Description
A Magnetic Particle Inspector (Metal) is a specialist who applies a magnetic field to metal products and weld areas using magnetic particle testing equipment to detect and evaluate surface or near-surface scratches, cracks, and defects. The work process includes degreasing and magnetizing the inspection target, applying magnetic particles, removing and washing excess magnetic particles, and recording and determining inspection results. Following standards such as JIS Z 2306 and ISO 9712, they compile reports on defect size and location and provide feedback to quality assurance and manufacturing departments. There is demand in a wide range of fields such as industrial machinery, automobiles, aircraft, and bridges, requiring high attention to detail and awareness of standards compliance.
Future Outlook
With increasing quality demands in manufacturing and strengthened safety regulations, demand for non-destructive testing technicians remains stable. Inspections for parts in automotive, aviation, and energy sectors are expected to increase. Advances in test automation and AI analysis technologies will make acquiring advanced skills key to market value.
