Zusammenfassung:	PURPOSE:To improve efficiency and quality by making a mobile time of a welding wire at the lower side longer than that at the upper side and performing oscillation so as to stop for a while at the upper end side and giving a magnetic field to the inside of a welding pool to perform the welding while stirring the inside of the pool. CONSTITUTION:The time to move from the oscillation lower end to the oscillation upper end is made longer than the time to move from the oscillation upper end to the oscillation lower end and the stopping time is taken at the upper end. Further, the magnetic stirring to push up molten metal 14 upward is performed by the stirring force obtained in the 90 deg. direction of a welding current 15 flowing in a molten pool P. A welding bead can be flattened and the efficiency and the quality can be improved by this method.
