摘要： The present invention relates to a laser apparatus using optical fibers for stable laser welding and a laser welding method using same. Hybrid ring mode-shaped laser beams, in which a central beam using fiber laser is positioned at the center of outer beams using diode laser, are used to perform welding by irradiating a to-be-welded portion of an object with the outer beams, the central beam, and the outer beams in this order. Thus, since the welding is performed using the central beam as a heat source in a state in which the to-be-welded portion of the object has been heated with a sufficient amount of heat input, the temperature gradient of the to-be-welded portion is low and solidification cracking does not occur. Also, problems such as spatter and voids can be minimized, and the laser welding is stable, and thus a quality of welding that is uniform and stable overall can be obtained.
