Abstract：
Complex steel component is divided into a curved the member variable cross-section cross five box type steel columns and large cross-section of solder ball grid box skylight beam support node structure. By analyzing the difficulty of complex steel components, features, deepen design optimized components and nodes; combined with existing equipment, the development of the assembly, welding technology and quality precision control measures; bulk component or node processing, research and development of dedicated equipment and tooling, to solve the processing problems, reduce the cost.
