  • Welding system implementing concurrent auto-dam fabrication
    Patent number: 9193002
    Abstract: A welding system is disclosed for use in closing a seam. The welding system may have a mount configured to hold a work piece having the seam to be welded, and a robotic welding device movable relative to the mount. The welding system may also have a controller in communication with the robotic welding device and configured to control the robotic welding device to sequentially generate a plurality of weld layers within the seam. Each weld layer may have at least one dam segment extending generally orthogonal to a length direction of the seam, and a main segment extending in the length direction.
    Type: Grant
