The invention belongs to the technical field of welding, and discloses an arc nozzle device for high-power laser-arc hybrid welding, which comprises a nozzle neck part and a nozzle end part which are connected, the nozzle neck part is close to one side of a welding gun, and the nozzle end part is close to one side of a weld pool; the nozzle end part is made of a tungsten-copper alloy material, and the copper element in the tungsten-copper alloy accounts for 6-30%. Meanwhile, the invention further provides a high-power laser-electric arc hybrid welding system. The high-temperature-resistant nozzle is convenient to adjust, high in reliability and high in adaptability, the problem that the nozzle is heated and melted in high-power-laser-arc hybrid welding can be solved, the continuous welding operation duration of the high-power-laser-arc hybrid welding can be greatly prolonged, the interruption frequency is reduced, and the welding efficiency is improved on the premise that the welding quality is guaranteed. 本发
