    Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic inspection method that can precisely and efficiently detect a defect etc., even in a place and a region where it is difficult to perform ultrasonic inspection, and to provide an ultrasonic inspection device.SOLUTION: An ultrasonic wave is transmitted from a phased array probe 2 to an inspection object part 101 to be inspected, and a reflected wave of the ultrasonic wave reflected on an inspection object part 101 is received to detect a defect of the inspection object part 101 with a signal of the received ultrasonic wave. The phased array probe 2 is arranged on one side with respect to a weld line L of a weld zone 101, and moved on a body 100 to be inspected along the weld line L. A plurality of ultrasonic waves which converge on an arbitrary point in a direction substantially orthogonal to the moving direction of the phased array probe 2 for each of a plurality of scanning positions are transmitted while made different in refraction angles. A sectional image including the direction substantially orthogonal to the moving direction and a plate thickness direction of the body to be inspected as axes is generated from signals of received reflected wave for each of the plurality of scanning positions. The defect is detected from the generated sectional images.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for inspecting a rail bottom face at a concealed part of a railway rail, which has higher resolution of a flaw than ever before and can detect a position of the flaw in a longitudinal direction of the rail and in a cross direction with respect to the longitudinal direction, and an inspection head used for the method.SOLUTION: An ultrasonic probe for a surface wave 13 is brought into contact with a rail bottom face 2a at an exposed part of a rail 2. The surface wave is made enter the rail bottom face 2a and is transmitted toward a concealed part 3, and the reflected surface wave is received by the probe 13. The probe 13 is oscillated or is moved in a crossing direction with respect to a longitudinal direction of the rail during the contacting state of the probe 13, so that a flaw at the concealed part 3 is inspected.
