Independently developed handheld laser welding machine, focusing on high-precision, high-efficiency and flexible welding needs. It can realize dead-angle-free welding of metal plates, pipes and special-shaped parts, and is widely used in hardware processing, kitchenware manufacturing, auto parts, electronic components and other fields. It replaces traditional argon arc welding and solves the problems of low welding efficiency, rough weld seams and serious deformation.
