摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic probe device capable of properly performing the ultrasonic inspection of inspection targets having various curvatures without applying mechanical load to a vibrator.
SOLUTION: A holder 15 is constituted so as to hold an ultrasonic probe 11 and provided with a shoe 14 having flexibility in a detachable manner. The shoe 14 is attached between the wedge 13 of the ultrasonic probe 11 and the inspection target by a holder 15. The ultrasonic probe 11 transmits on ultrasonic wave to the inspection target from the vibrator 12 through the wedge 13 and the shoe 14 and receives the reflected wave from the inspection target by the vibrator 12 through the shoe 14 and the wedge 13. The shoe 14 has various shapes so that its leading end is matched with the surface shape of the inspection target and can be replaced so as to be matched with the surface shape of the inspection target.

摘要： PROBLEM TO BE SOLVED: To precisely detect the amount of weld penetration shortage in a fillet weld section.
SOLUTION: A spot focusing angle probe and a distance sensor are moved back and forth in a direction perpendicular to a weld line of the fillet weld section, wherein fillet welding is carried out between two base materials so that one base material is coupled obliquely with the other base material, and a reflection echo from a head section of the weld penetration shortage in the fillet weld section is detected, and the distance values from the spot focusing angle probe to two different locations in the one base material are measured; and a position of the head section of the weld penetration shortage is obtained from the path length of an ultrasonic beam, derived from the detected reflection echo in relation to the position of the spot-focusing angle probe, and an angle value between the two base materials is obtained on the basis of the distance values from the spot focusing angle probe to the two different positions in the one base material; then a position of the start section of the weld penetration shortage is obtained on the basis of the angle value in relation to a position of the spot focusing angle probe; and the amount of weld penetration shortage is obtained from positions of the head section and the start section of the weld penetration shortage.
