Abstract
The present invention relates to a high energy density beam welding system using molten metal droplet jetting. The present invention includes a beam emitting unit for emitting a high energy density beam onto a welded portion on a target object; and a molten metal droplet jetting unit for generating molten metal droplets to transfer or spray the molten metal droplets onto the welded portion on the target object, which follows a path of the beam emitting unit. Thus, it has advantages of widening a range of applications and enhancing the productivity and the quality in that a welding can be performed at a high junction efficiency even where a gap is wide, a loss in the high density energy beam is small, and heat distortions of the welded portion can be minimized.
