摘要： PROBLEM TO BE SOLVED: To provide a flaw detection method capable of simply detecting the flaw produced in an inspection target part difficult to inspect, such as, a welded part at a high speed in a non-contact state, regardless of the thickness and the material of an inspection target, the shape of the welded part, or the like, and to provide a flaw detector used therein.
SOLUTION: Ultrasonic waves are transmitted to the inspection target from a probe, while the ultrasonic waves that propagate through the inspection target are received, to detect the flaw of the inspection target part by the receiving signal. The probe is scanned along the inspection target part in a non-contact state, and the respective receiving signals of a plurality of kinds of the ultrasonic waves propagated through the inspection target are displayed as the image of at least either of a B-scope or a C-scope. The flaw is detected on the basis of the existence of the change part R2 in the image.

SOLUTION: Axial forces acting on a hollow expansion-type rock bolt are measured. The rock bolt has a measuring rod 50 fastened or arranged along a tube body 20. At the construction of the rock bolt, ultrasonic measurement is previously performed by transmitting ultrasonic waves from an incident part 11, an exposed part of the measuring rod 50, receiving reflected waves from gauge marks, and determining the reception time differences of the reflected waves from the gauge marks. Ultrasonic measurement is performed anew to compute axial forces on the basis of changes in reception time differences.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic inspection method and an ultrasonic inspection method, capable of inspecting the inside of an inspection object, even when there are surfaces of the inspection object having irregularities or are made sloped.
SOLUTION: Ultrasonic waves are transmitted and received by a probe 10, thereby detecting a defect S or flaws of the inspection object 100. A focus-type probe is used as the probe, and the focal point F of the probe is set at a position of an object to be detected being beyond the downstream side of an ultrasonic transmission. The probe makes the ultrasonic waves expand and propagate radially inside the inspection object, whereby a defect inspection can be carried out by projecting the ultrasonic waves onto the defect S or the like existing inside the inspection object, even if the surface of the inspection object has irregularities or is made sloped. If the probe concurrently make the part operate transmission and reception, the defect position is easily specified. Similarly, the defect position is easily specified, by displaying an image obtained by received ultrasonic waves in at least two dimensions.
