Maven robotic laser welding machine is a fiber laser that couples a high-energy laser beam with a robotic laser as the moving platform for welding. Any spatial trajectory can be welded. The multi-purpose laser welding machine can be programmed to weld parts that are difficult to access with ordinary laser welding machines, providing maximum welding flexibility. The laser beam can be split in time and energy, enabling simultaneous processing of multiple beams and improving welding productivity.
