摘要： The present invention provides a method and apparatus for an ultrasonic inspection of a penetration of a reactor pressure vessel, especially, a welded portion of the penetration. In the ultrasonic inspection, a position (inspection position) of an ultrasonic probe relative to a portion to be inspected can be identified without an effect of the surface of a portion to be inspected.The ultrasonic probe of the ultrasonic inspection apparatus, which is pushed onto the outer surface of the reactor pressure vessel, transmits and receives an ultrasonic wave to and from a penetration having a welded portion while changing an incident angle of the ultrasonic wave. Based on a result of reception of an echo obtained by the reflection of the ultrasonic wave on the inner surface of the penetration, an inclination angle of the penetration relative to a wall surface of the reactor pressure vessel is measured. A circumferential direction position of the penetration, which corresponds to the inclination angle, is calculated based on the relationship of an inclination angle and a circumferential direction position, which have been calculated in advance. Then, the circumferential direction position can be obtained as information on the inspection position.

摘要： An ultrasonic inspection method and an ultrasonic inspection device allow three-dimensional inspection data and three-dimensional shape data to be appropriately positioned on a display screen and allow a defect echo and a shape echo to be quickly identified even when information on the relative positions of a probe and an object to be inspected is not provided. The ultrasonic inspection data that is generated from the waveforms of ultrasonic waves received by an ultrasonic probe is compared with a plurality of ultrasonic propagation data pieces calculated by a ray tracing method on the basis of the three-dimensional shape data on an object to be inspected. The position of the three-dimensional inspection data or the three-dimensional shape data is moved relative to the other data position on the basis of the comparison results, thereby displaying the three-dimensional inspection data and the three-dimensional shape data while overlapping each other.

摘要： An apparatus and a method for ultrasonic testing obtains high-resolution and high-S/N ratio testing results by driving a number of piezoelectric elements using fewer pulsers and receivers in comparison with the number of elements composing an array transducer. A sensor information setter sets a plurality of piezoelectric element groups used for transmission and a plurality of piezoelectric element groups used for reception among the plurality of piezoelectric elements composing an ultrasonic array transducer. A computer transmits an ultrasonic wave from the element cluster set for transmission, and stores an ultrasonic wave received by the element cluster set for reception. The procedure is repeated including different element cluster sets for transmission and reception to obtain first receive signals. The first receive signals are summed to obtain a second receive signal; and the second receive signal is displayed with reference to the sensor center position on a display unit.

摘要： An ultrasonic probe issues an ultrasonic wave to an object, receives a reflected wave from an object, and is provided with multiple piezoelectric elements. A three-dimensional display section displays three-dimensional flaw detection data superimposed on three-dimensional shape data of an object. The computer acquires a reflected ultrasonic wave signal from a reference object (reference). Based on the acquired signal, the computer corrects a reflected ultrasonic wave signal acquired from another object having the same material and shape as the reference. The computer allows the three-dimensional display section to display three-dimensional flaw detection data generated from a reflected ultrasonic wave signal resulting from a difference between a reference and an object.
