    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for evaluating a defect of a tubular object, capable of not only speedily detecting even the defect whose defective volume is small, but also identifying inner and outer surfaces having the defect.
    SOLUTION: The method employs a sensor equipped with a DC magnetizing coil 11 and an eddy-current flaw detection coil 12. In the method, an eddy-current flaw detection is carried out for a test tube which is or is equivalent of the tubular object 100 and has a plurality of kinds of simulated defects previously disposed on its inner and outer surfaces 101, 102, while DC magnetizing the test tube by using the sensor, and then the intensity of above DC magnetization and a test frequency of the eddy-current flaw detection coil 12 are selected so that the simulated defects can be detected, and the simulated defects located on any of the inner and outer surfaces 101, 102 of the tubular object 100 can be identified, by using both effects of a magnetic permeability change and an occurrence of eddy current E, E', and then the sensor is inserted into the tubular object 100, and the eddy-current flaw detection is carried out, while DC magnetizing the tubular object 100 in the condition of the selected DC magnetization intensity and test frequency. Which one of the inner and outer surfaces 101, 102 of the tubular object 100 has the defect is identified by using a detection signal of the eddy-current flaw detection coil 12.

    IPC: G01N29/04

    Abstract: PROBLEM TO BE SOLVED: To provide a method for inspecting a joined portion capable of accurately inspecting a joined portion by ultrasonic waves and reducing restrictions on the arrangement position of a probe.
    SOLUTION: A first ultrasonic flaw detection is performed by emitting ultrasonic waves from a probe 40 of an ultrasonic flaw detection device to a bonding face between a second flange part 14B of an insert 14 and a top board part 12B of a component 12, and receiving reflected waves of the ultrasonic waves reflected by the bonding face to acquire an image of the condition of the bonding face. Next, a second ultrasonic flaw inspection is performed by applying a load to the insert 14 and removing the load to acquire an image of the condition of the bonding face. If there is a bonding defect, a load in a direction to separate is applied to the bonding face to make a gap in a portion with the bonding defect. Since the reflection waves from a normal bonding portion are different from the reflection waves from the portion with the gap, it is possible to specify the bonding defect portion from the image.

    Abstract: PROBLEM TO BE SOLVED: To provide a method of detecting an end of defect or the like and a detection device for detecting the end of defect or the like for conveniently and accurately detecting the end of defect or the like. SOLUTION: Ultrasonic waves are transmitted to and received from a defect or the like 200 by oscillators 8, 9 to thereby detect an end 200a toward the test reference direction F of the defect or the like 200. A pair of oscillators 8, 9 are disposed in plane-symmetry with respect to a reference surface 300 perpendicular to the test reference direction F. The pair of oscillators 8, 9 are shifted to the test reference direction F and the pair of oscillators 8, 9 are made to transmit and receive the ultrasonic waves. A two-dimensional image of received signal is recorded and the end 200a is detected from the crossing section E of defect signal in the synthetic two-dimensional image formed by synthesizing the two-dimensional image recording the oscillators 8, 9.

    Abstract: PROBLEM TO BE SOLVED: To provide a conduit inspection method and a conduit inspection device capable of determining an abnormality of a conduit safely, inexpensively and accurately, without breaking the conduit.
    SOLUTION: An acoustic signal is transmitted inside a pipe from a transmitter mounted on one end of the pipe, and a reflected signal reflected by the inside of the pipe is received by a receiver mounted similarly on one end of the pipe. An an abnormality of the conduit is determined by the received reflected signal. An abnormal signal is extracted from the reflected signal by a mutual correlation function between the reflected signal and a reference waveform. Phase determination is performed by a phase of the extracted abnormal signal and a phase of the reference waveform, to thereby determine the abnormality of the conduit.
