| 摘要： | The application of robotics provides good potential to increase welding productivity, reduce dependence on skilled labor and improve the competitive position of U.S. shipyards. However, shipyard applications have generally been limited to small part sizes and repetitive batch lots. Hitachi Zosen of Japan has made considerable progress in developing and applying portable robotic welding equipment for welding primary ship's structure. These robots are not the conventional teach-playback variety, but rather a numerically-controlled (NC) robot that utilizes off-line programming making it particularly adaptable to high volume, non-repetitious welding tasks. The robot system was designed for ease of handling, minimal set-up time and operator intervention, and for use in smaller confined spaces. Unskilled operators rather than experienced welders can be used because of the robots off-line programming feature and computer control of the welding operation. An initial technical evaluation, including a trip to Japan to observe the portable welding robots in operation, was completed under funding from the National Shipbuilding Research Program (NSRP). The evaluation concluded that the portable welding robot offers excellent potential in U.S. shipyards to reduce structural welding costs and improve overall productivity for commercial and naval ship construction. / NOTE:Conference paper. |
