APPARATUS AND METHOD FOR PREDICTING WELD QUALITY

An apparatus for predicting weld quality includes an image sensor acquiring an image of a welding portion of a workpiece, a storage storing a shape detection model, a depth prediction model and a strength prediction model, and a controller configured to acquire shapes of a melt pool and a keyhole by receiving the image and inputting the image to the shape detection model, acquire a penetration depth of the keyhole by inputting the shapes of the melt pool and the keyhole to the depth prediction model, and acquire a tensile strength by inputting one of the shape of the melt pool, the shape of the keyhole and the shapes of the melt pool and the keyhole and the penetration depth of the keyhole to the strength prediction model. The weld quality of all products may be predicted during a welding process.
