PURPOSE:To increase a welding speed and to improve welding efficiency by oscillating relatively a filler metal supplied to a torch electrode of arc welding to apply a stirring effect to a molten pool thereby preventing the local cooling of the molten pool and improving the welding. CONSTITUTION:The filler wire 4 supplied to the torch 6 electrode of an arc welding device is relatively oscillated by a slider 10. The stirring effect is provided to the molten pool 2 by the oscillating wire 4, by which the local cooling of the molten pool is prevented and the molten pool is uniformly cooled to form a satisfactory weld zone. The melting speed of the wire 4 is increased by the stirring to improve the welding efficiency.
