Eight Axis Gantry Intelligent Workstation is mainly used for the welding production of plate unit structure type workpieces in ships, bridges, and environmental protection equipment. The eight axis gantry workstation is compatible with the adaptability of ground rails, seven axis cantilevers, eight axis cantilevers, and seven axis gantry workstations. 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.
