Summary
Specialist in non-destructive testing who applies penetrant liquid to the surface of metal products to detect fine cracks and defects.
Description
Penetrant Testing Inspectors (Metal) are non-destructive testing technicians who detect surface defects in metal products. In manufacturing lines or inspection areas, they apply penetrant and developer liquids, clean, and develop according to JIS standards, then visually inspect for cracks and linear defects using the naked eye or magnifying glass. They manage inspection procedures, adjust test conditions, create inspection records, and prepare quality evaluation reports to ensure product safety and reliability. In recent years, integration with automated equipment and image processing technology has advanced, requiring technicians to have high expertise and continuous learning.
Future Outlook
With the advancement of manufacturing and increasing quality demands, the demand for non-destructive testing remains stable. Integration with inspection automation and AI technology requires advanced knowledge from technicians.
