HEAD AND APPARATUS FOR ULTRASONIC FLAW DETECTION

摘要

PROBLEM TO BE SOLVED: To easily perform an ultrasonic inspection even in a high-radiation environment. SOLUTION: The front of a shoe material 1a and that of a shoe material 1b are formed to be arc-shaped so as to be capable of coming into contact with a prescribed position in the circumferential part at a canister mainframe 3 having a weld 5 to be inspected, a pool 7a and a pool 7b to which water is supplied and from which the supplied water can be returned are formed on the arc-shaped face, and an ultrasonic probe 4a and an ultrasonic probe 4b which comprise a casing formed of a highly radiation-resistant material are attached to the back of the shoe material 1a and that of the shoe material 1b.
