摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flaw detection method and an apparatus which can be handled easily and which can speedily acquire flaw detection images with high resolution and high S/N ratio.SOLUTION: In an ultrasonic flaw detection method, an array-type ultrasonic sensor 101 is moved sequentially from a position 101A to a position 101B, and from the position 101B to a position 101C by scanning means 107, while an incident angle of an ultrasonic wave 108 oscillated from the array-type ultrasonic sensor 101 is being swung to detect flaws inside an object 100 to be inspected by a sector scan. Flaw detection images, acquired each time by moving the array type ultrasonic sensor 101, are shifted while an moving amount of the array-type ultrasonic sensor 101 are added or averaged and formed as visual images as processing images 103C. Since focusing effect of the ultrasonic wave 108 can be acquired, without finely setting depth of focus in the object 100 to be inspected, the flaw detection images can be obtained with high resolution at all the depth positions of a flaw detection region and high-accuracy nondestructive inspection can be conducted.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flaw detection method for evaluating in detail the size of a defect in a body to be inspected.
SOLUTION: According to this ultrasonic flaw detection method, an ultrasonic wave is caused to propagate from an array sensor 102 of an ultrasonic flaw detector to the interior of the body 101 to be inspected to acquire reception signals which are echoes reflected by a reflection source 103 such as cracks in the body 101 and the size of the reflection source 103 of the body 101 is evaluated from the reception signal. The ultrasonic wave is mode-converted during its propagation and reflected by the reflection source, resultantly producing a mode conversion echo. A signal intensity ratio is found between the signal intensity of a reception signal of the conversion echo, that is, the intensity 114 of the conversion echo, and, among the echoes, the signal intensity of a reception signal of another echo having a propagation path or propagation time different from what the conversion echo has, for example, the signal intensity 113 of longitudinal wave direct echo. The found intensity ratio is collated with a master curve 116 on a graph for relating a signal intensity ratio previously found by experiment or calculation to the size of a reflection source, thereby finding the size of the reflection source.
