PURPOSE:To easily weld a work of a three-dimensional weld line by providing a driving part for rotating a filler wire supply device on a working head, and positioning a wire supply nozzle in front of the weld line of a butt part by an NC controller. CONSTITUTION:On a working head 8 of a laser welding machine having the degree of freedom of five axes, a filler wire supply device 18 being freely rotatable coaxially with this head 8 is provided, and on the working head 8, a driving part 16 for rotating the filler wire supply device 18 is provided. Subsequently, a wire supply nozzle 18d of the filler wire supply device is positioned in front of a weld line 22a of a butt part by an NC controller 23.
