    摘要: To facilitate overlay welding while securing a certain hardness of an overlaid portion and preventing welding defects, an overlay welding method for performing overlay welding on a surface P to be overlaid of a base material 50 includes a preparing step of forming a bottomed depression 51, with the surface P to be overlaid being a circumferential surface 51a thereof, and an overlaying step at which a filler material is fed toward a bottom face 51b of the depression 51, and a laser beam as a heat source is irradiated on the bottom face 51b of the depression 51 to which the filler material is fed, thereby forming an overlaid portion W reaching the surface P to be overlaid, while filling the bottom face 51b of the depression 51 with a melted filler material.
