Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a laser beam buildup welding method by which the efficiency of laser beam buildup welding is improved and also the generation of defects in a buildup layer can be suppressed.SOLUTION: A laser beam buildup welding system 1 performs buildup welding by charging a laser beam onto the surface of a base material and supplying a welding material on a face to be irradiated with the laser beam. In this laser beam buildup welding system 1, the face to be irradiated with the laser beam on the surface S of the base material is made into an extended face A to be irradiated which is extended in accordance with the surface to be welded. Within the extended face to be irradiated on the surface S of the base material, the welding material of amount in accordance with the distribution of heat quantity of the extended surface to be irradiated is supplied.
