PURPOSE:To generate a fine droplet, and to execute a stable welding for generating no spatter, by giving an ultrasonic vibration in the direction for crossing an axis, to a welding wire. CONSTITUTION:By a DC welding power source 9, an arc 3 is generated between a welding wire 4 and a base metal 2, and a droplet is generated in the tip of the wire 4. Subsequently, an ultrasonic vibration which has been generated by an ultrasonic vibrator 11 is transmitted to a feeding chip 5 by a connecting material 12, the welding wire 4 is vibrated in the direction for crossing an axis, and the droplet is migrated as a fine particle to the base metal 2. In this way, a stable welding for generating no spatter can be executed.
