Abstract
An ultrasonic flaw detection apparatus includes: a seam detection unit that captures a thermal image of a welded seam portion of an electric resistance welded pipe; an ultrasonic flaw detection sensor head that includes an ultrasonic probe that performs ultrasonic flaw detection on the welded seam portion; a seam position calculation unit that calculates a seam position and a bead cutting position of the electric resistance welded pipe; a bead cutting band detection unit that detects a bead cutting band of the electric resistance welded pipe; a bead cutting position calculation unit that calculates a bead cutting position of the electric resistance welded pipe; a tracking movement amount calculation unit that calculates a tracking movement amount of the ultrasonic flaw detection sensor head; and a sensor head driving unit that moves the ultrasonic flaw detection sensor head to track the welded seam portion according to the tracking movement amount.
