Abstract:
A head attachment part (31) is attached to a welding head of a laser welder. The head attachment part (31) has an opening (31a) through which a laser beam that is emitted from the welding head and that illuminates a welding location passes. A gas spray nozzle (32) is attached at a side of the head attachment part (31), and sprays a shield gas to the welding location. The gas spray nozzle (32) has a main nozzle (321), which is arranged on the side closer to the head attachment part (31), and is supplied with the shield gas by a first gas pipe (311), and a sub-nozzle (322), which is arranged so as to be adjacent to the main nozzle (321) and farther away from the head attachment part (31) than the main nozzle (321), and is supplied with the shield gas by a second gas pipe (312). The sub-nozzle (322) is attached to the main nozzle (321) in a removable manner.
