Welding device (1) and a method for automatic multiple-bead welding are described. A line illumination member (10) is arranged to illuminate the joint by scanning a light beam across the joint line (8). A camera (16) is arranged for the registration of line images of the joint when it is illuminated with the scanned light beam. The locations of the edges (12, 13) of the joint are determined by means of triangulation based on the registered line image. The welding device (1) comprises a stereo image member arranged to register photometric stereo images of the joint substantially simultaneously with the registration of the line images. The welding device (1) is arranged to, during welding of a weld joint with a plurality of weld beads, control the welding head (9) in dependence on both stereo images and line images.
