The automatic magnetic particle examination equipment used for the defect detecting examination of a steel structure welding part is developed. Magnetic particle examination which consists of complicated magnetic paricle spraying work and defective judging work by viewing had required skill and inspection time. Therefore, in the long examination of welding length like a large-sized structure, laborsaving had become a subject. By this research, the automatic magnetic particle examination equipment which paid its attention to automation of the magnetic particle spraying work which was being conventionally done by handmade business and automation of the defective discernment judging which was being performed visually is made as an experiment, and the result evaluated by the actual steel structure etc. is reported.
