摘要： PROBLEM TO BE SOLVED: To solve such a problem that much time and labor are needed for additional perpendicular directional scan to the weld line of a welded joint part because of the incapability of detecting a correct position of a defect in a perpendicular direction in the scanning direction.
SOLUTION: The quick flaw detection can be performed as follows: the ultrasonic sounds 9, 10 are transmitted from one side of different position of the flaw detection part 2 toward the flaw detection part 2 from the 2 transmission probes 3, 4; the diffraction waves 11, 12 of the ultrasonic sounds 9, 10, diffracted by the defect e are received by the reception probes 5, 6 in combination with the transmission probes 3, 4 arranged on the different position of the other side of the flaw detection part 2; and the position of the defect e is determined from the difference of transmission time of the diffraction waves 11, 12 received by the reception probes 5, 6. Thereby, the deviation Δy of the defect e in the perpendicular direction from the flaw detection part 2 can be easily detected.

摘要： PROBLEM TO BE SOLVED: To provide friction stir equipment capable of suppressing the unevenness of quality of an objective material, which is caused by the influence from disturbance such as an outside air temperature. SOLUTION: A controller determines a rotation resistance force around an axis exerted to a rotary tool 30 from a material 33 to be joined, based on the current value given to a motor for rotating the rotary tool 30, and judges, as a shoulder part contact time t2, the time when the rotation resistance force takes the maximum value. A travelling start time when the movement of the rotary tool 30 in the travelling direction is started is decided based on the shoulder part contact time t2. The state of friction stirring after the shoulder part contact time t2 is less influenced from the disturbance. Accordingly, by deciding a travelling start time t3 of the rotary tool 30 based on the shoulder part contact time t2, the travelling of the rotary tool 30 is started when a softening state reachs a stable just enough state, so that the quality of the material 33 to be joined is stabilized after joining.

摘要： PROBLEM TO BE SOLVED: To overcome a difficulty in carrying out an ultrasonic test while disposing an ultrasonic probe at an appropriate position in accordance with a body to be tested, and to solve such problems that rapid works are difficult in the ultrasonic test, and evaluation precision is decreased.
SOLUTION: In the method, the ultrasonic test is carried out by using an ultrasonic wave having a prescribed intensity H generated by the ultrasonic probe 5 being disposed at a plurality of prescribed positions in relation to a defect 4 disposed at a prescribed position of the body to be tested 1 having a prescribed thickness. Then, a relation between depth values of the ultrasonic axis crossover points and the ultrasonic intensity H is obtained from the ultrasonic intensity H at each position where the ultrasonic probe carries out the ultrasonic test. The relation between the depth of ultrasonic axis crossover point and the ultrasonic intensity H is converted into a relative positional relation between a defect depth v and the ultrasonic axis crossover point 3, and a positional arrangement of the ultrasonic probe 5 suitable for the ultrasonic test of the body to be tested 1 is selected based on the relative positional relation between the defect depth v and the ultrasonic axis crossover point 3, thereby obtaining an effective probe arrangement and carrying out the ultrasonic test stably.

摘要： PROBLEM TO BE SOLVED: To solve the problem wherein scanning in the orthogonal direction to the weld line of a welded joint part is additionally required because a flaw position in the scanning rectangular direction cannot be detected accurately, to thereby require much time and labor. SOLUTION: Ultrasonic waves 9, 10 are transmitted by two transmitting search units 3, 4 toward a flaw examination part 2 from different positions on one side of the flaw examination part 2, and diffracted waves 11, 12 from the flaw e of the ultrasonic waves 9, 10 are received by receiving search units 5, 6 on different positions on the other side of the flaw examination part 2, which are pairs of the transmitting search units 3, 4. Then, the flaw e position is determined from the propagation time difference of the diffracted waves 11, 12 received by the receiving search units 5, 6, to thereby easily detect the shift quantity Δy of the flaw e in the scanning rectangular direction of the flaw examination part 2, and to enable a quick ultrasonic examination work.
