A Study On the Magnetic Particle Testing Method for Coated Welding points

Coated welding points are eliminated for Open-Inspection of above-ground storage tanks which should be inspected periodically in accordance with the Hazmat-treatment Safety Act. But it was speculated on this study that it causes such huge economical losses in terms of manpower and materials that applicable to magnetic particle testing. As a result, it was concluded that the magnetic particle testing is applicable to the coating depth below $50{\mu}m$.
