Abstract

PURPOSE: To make automatic and accurate detection of flaws by disposing one vertical probe and two bevel probes on the inside surface at the end of a revolving steel pipe, and making the ultrasonic oscillation direction of the bevel probe on the side upward of the revolving direction reverse from the revolving direction and making that on the downward side in the same direction as the revolving direction.
