摘要： PROBLEM TO BE SOLVED: To keep the detection sensitivity of a flaw while displaying the accurate position of a reflecting source even in the case where a coating material and a material to be inspected change in thickness.
SOLUTION: A first step (steps 101-107) for measuring the thicknesses of both the coating material and the material to be inspected, a second step (step 108) for altering the delay times set to the respective vibration elements of the array probe of an ultrasonic inspection device, and a third step (step 109) for transmitting an ultrasonic wave on the basis of the delay times after alteration to inspect the flaw are executed and, even if the thicknesses of both of the coating material and the material to be inspected change, the ultrasonic waves transmitted from the respective vibration elements are converged to the position of the inspection target in the material to be inspected. Further, the thickness of the coating material is measured on the basis of the ultrasonic waves and the position of the boundary of the coating material and the material to be inspected (the surface of the material to be inspected) is specified on the basis of the measuring result while the position of the reflecting source in the material to be inspected is precisely calculated to be precisely displayed on the display device of the ultrasonic inspection device.

摘要： PROBLEM TO BE SOLVED: To provide a method for certainly evaluating the depth of a crack even at all cases of the direction of the crack in inspection using an ultrasonic array sensor.
SOLUTION: In this ultrasonic inspection method for evaluating integrity of a specimen 5 using the ultrasonic array sensor, a transmission ultrasonic array sensor 1 and a detection ultrasonic array sensor 2 are arranged on the surface of the specimen so that the outer product direction (X-direction), which is formed by the longitudinal direction of the oscillators 3 of the respective ultrasonic array sensors 1 and 2 and the direction of the straight line 6 passing the center positions of the oscillator surfaces 8 of the ultrasonic array sensors 1 and 2, crosses the normal line direction of the surface of the specimen at a right angle. By this arrangement, an ultrasonic beam can be scanned with respect to the X-direction, a converged beam can be thrown on the crack inclined with respect to the X-ray direction. Further, since detection signal processing considering a delay time with respect to the X-ray direction is enabled, the detection intensity of a weak end part echo is enhanced and the healthiness of the specimen ensuring a high SN ratio can be evaluated.
