Abstract: The present invention relates to a laser-rotating arc hybrid welding system and a welding method using the system. The laser-rotating arc hybrid welding system of the present invention includes an arc discharge unit (2) for generating arc discharge along an area to be welded. A laser generation unit (4) radiates laser light onto the area to be welded. A rotating device (24) rotates the arc discharge unit (2). In the welding method using the laser-rotating arc hybrid welding system, a plurality of parent metals is aligned with a welding location. A laser-rotating arc hybrid welding system is located with respect to an area to be welded, arc discharge is generated while an arc discharge unit is rotated at a predetermined turning radius, and laser light is subsequently radiated using a laser generation unit.
