To provide a composite welding device which obtains stable welding quality at the start of composite welding and prevents a crater from being recessed and excessively growing at the end of welding while securing sufficient welding penetration.
A composite welding device includes: a wire feeding means 7 for feeding a welding wire; a welding power source device 10 for generating arc between a welding wire 9 and a welding position; a laser device 1 for generating a laser beam 5 to irradiate the welding position with the laser beam; and a control means for controlling the wire feeding means 7, the welding power source device 10, and the laser device 1. The control means 12 stops electric power to be supplied to the welding wire 9 by controlling the welding power source device 10 at the end of welding, and stops the laser beam 5 and the welding wire 9 after feeding the welding wire 9 in a pulsed form by controlling the wire feeding means 7.
