WELDED SECTION EXAMINING DEVICE

The present invention relates to a welded section examining device. In order to examine whether welding is good or bad of a welded section (32) joining tip portions of electrical conductors projectingfrom slots of a stator core, a welded section examining device (10) includes a camera (40), a discriminating unit (56), a wavelength-converting sheet (44), and a masking member (46). The camera (40)images the welded section (32). The discriminating unit (56) performs discrimination of whether welding is good or bad based on an outline of the welded section (32) recognized from an image of the welded section (32) imaged by the camera (40). The wavelength-converting sheet irradiates the welded section (32) with a light, from a rear surface (54) side of an imaging target surface. The masking member (46) is interposed between the wavelength-converting sheet (44) and the rear surface (54) of the welded section (32), such that the outline of the welded section (32) is imaged in the camera (49)in an emphasized state. 本发
