Eight Axis Cantilever Intelligent Workstation is mainly used for the welding production of bridge and ship plate unit structures and other types of workpieces. The eight axis cantilever workstation is compatible with the adaptability of ground rails and seven axis cantilever workstations, improving the adaptability in the width direction. The system deeply integrates welding processes, accurately locates component welds through a visual system, and automatically generates welding programs and executes welding based on the obtained weld coordinate information through the integrated fabric welding expert library. For flat angle welds, vertical angle welds, and multi-layer and multi pass welds with arbitrary placement of workpieces, precise and fast welding can be achieved without programming, teaching, and graphic import. The workstation has auxiliary functions such as arc tracking, automatic gun cleaning, and long-term continuous welding
