Abstract
Provided is a laser welding inspection apparatus capable of improving the accuracy for determining the welding defect. The laser welding inspection apparatus includes a head which irradiates a welded portion of a workpiece with a laser beam for inspection, an optical receiver which receives a return light of the laser beam for inspection from the welded portion, an optical system which adjusts at least a focal diameter of the laser beam for inspection applied to the welded portion and a region where the return light from the welded portion is recognized, and a controller which controls the optical system and determines, based on intensity of the return light, whether a welding defect exists in the welded portion. The controller controls the optical system so that a diameter of the region is not more than 1.5 times as large as the focal diameter.
