摘要： PROBLEM TO BE SOLVED: To provide a method of inspecting flaws by ultrasonic waves that can be executed without problems, even under the condition that cannot be coped with conventional, general angle beam flaw detection methods, and to provide a probe unit for the method of inspecting flaws by ultrasonic waves. SOLUTION: A probe 4 that transmits SV waves, set within a refraction angle range of 78-88°, is disposed on a surface at the side of a bead 3 on a main plate 1. With the tip of the probe 4 being aligned at a position of the starting end 3a of the bead 3 (or a position within 3 mm from the starting end 3a), ultrasonic waves are transmitted; receiving signals containing reflected echoes of diffraction waves that advance, while expanding in the bead 3 by diffraction phenomenon, are acquired; and the dimensions of a non-welded section 5 are estimated.
