Zusammenfassung:	PROBLEM TO BE SOLVED: To improve reliability in welding.SOLUTION: In a base material M, a front side removing region Ff adjacent to a molten pool P which is melted by receiving welding energy and including a front side region in a welding direction to the molten pool P is irradiated with a laser beam to scatter particles for forming an oxide film of the surface of the base material.
