In this production line, bodywork components are also joined using a gas-protected welding process. The robot working area where these welds are produced, is enlarged beyond the size required for the operation. The line includes a workstation (1) with a welding robot (4) having resistance spot welding jaws. A second workstation (2) includes two or more welding robots with protective gas welding torches (5). The working area for these robots is larger than that required for operations on the bodywork (8). In the second workstation (2), on each side of and close to the conveyor (7), the same number of welding robots is arranged. Each welding robot of the second workstation can be moved parallel to the conveying direction. Near each of these welding robots, at the end of its travel and outside its working region, a maintenance zone is provided. This zone is accessible independently of the maintenance region and working region of the other welding robots (5) on the same processing side. The second workstation (2) includes two planes. The welding robots are arranged on the plane at conveyor height, the welding wire pulleys are arranged on the next higher plane. Near the welding wire pulleys, there are further supply- and control units for each welding robot of this workstation. An independent claim IS INCLUDED FOR the corresponding production line. |
