WELDED PART INSPECTION DEVICE AND METHOD FOR INSPECTING WELDED PART

摘要

PROBLEM TO BE SOLVED: To provide a method enabling inspection of a welded part with simple processes where materials are filler-welded together.SOLUTION: A welded part inspection device 100 according to an embodiment of the present invention, includes: a vibration body 10 that applies shock on a first welded material of the first and a second welded materials welded together; a sensor 12 that measures a second vibration intensity of a shock wave having passed from the first welded material to the second welded material through the welded part due to the shock; a sensor 412 that measures a second vibration intensity of a shock wave having passed through the first welded material due to the shock; and an operating unit 72 that operates a parameter for inspecting the welded part using a ratio between the first and second vibration intensities measured.
