초록 ▼

The distance sensor means and the ultrasonic probe are integrally coupled to each other in such a manner that a preceding scanning line to a current scanning line which is scanned by the ultrasonic probe is scanned by the distance sensor means, and the shape-measurement scanning operation of the distance sensor means and the flaw-detection scanning operation of the ultrasonic probe are performed in parallel with each other. A flaw detection area is divided into plural sub-areas, and plural storing areas are arranged in a mesh form in one-to-one correspondence to the sub-areas, only one shape information of position storing area including the flaw detection area being stored in each of the storing areas. The position and orientation of the ultrasonic probe at each flaw detection point is controlled using the stored shape information.

대표청구항 ▼

An ultrasonic flaw detector comprising: an ultrasonic probe for radiating an ultrasonic flaw-detecting signal onto each flaw detection point within a flaw detection area which is specified on a surface of a target, and receiving an ultrasonic wave reflected from the detection point; distance sensor means for radiating a distance measuring signal onto a measuring point within a position storing area including the flaw detection area to detect a distance between the measuring point and said distance means; coupling means for integrally coupling said distance sensor means and said ultrasonic probe in such a manner that said distance sensor means scans a preceding scanning line; position and orientation control means for controlling position and orientation of said ultrasonic probe and said distance sensor means; shape information calculation means for calculating information on the shape of the position storing area including the flaw detection area on the basis of a detection result of said distance sensor means and a current position of said distance sensor means; storing means for storing the shape information; position and orientation calculation means for calculating position and orientation of said ultrasonic probe on the basis of the shape information stored in said storing means to thereby radiate the flaw detecting signal onto the measuring point at predetermined angle and distance from said ultrasonic probe; and control means for performing a shape-measurement scanning operation of said distance sensor means and a flaw-detection scanning operation of said ultrasonic probe in parallel with each other.
