Abstract: An appearance inspection apparatus includes a shape measurement unit configured to measure the three-dimensional shape of a weld and a data processor configured to process shape data acquired by the shape measurement unit. The data processor includes a shape data processor configured to correct a resolution of the shape data, a learning data set generator configured to generate a plurality of learning data sets by performing data augmentation on multiple pieces of sample shape data acquired in advance, a determination model generator configured to generate a determination model using the plurality of learning data sets, and a first determination unit configured to determine whether the shape of the weld is good or bad based on the shape data having the corrected resolution and the determination model.

Abstract: A welding system includes a welding apparatus and an appearance inspection apparatus. The appearance inspection apparatus includes: a shape measurement unit that measures the shape of a weld; an image processor that generates image data based on data of the shape; a determination unit that determines whether the shape of the weld is good or bad based on the image data and a determination model; and a feedback unit that extracts shape defect information if the result of the determination by the determination unit is negative. An output controller of the welding apparatus corrects a welding condition for a workpiece based on the shape defect information extracted by the feedback unit.
