Abstract
A cleaning processing jig is inserted into a bolt heater hole, and pollution such as extraneous matter on an inner surface of the hole is removed by a waste cloth. A penetration processing jig is inserted into the hole, and the penetrant is made to uniformly penetrate into the inner surface by a sponge onto which a penetrant is applied. Then, a developing processing jig is inserted into the hole, and the inner surface is developed by injecting a developer toward the inner surface from an injection tip provided on a head. When a predetermined time elapses after the developing processing, a visual inspection tool in which a visible head is attached to a tip of a pipe is inserted into the hole, and the inner surface is visually inspected through a light pipe connected to the visible head.
