| description | An overlay welding method includes irradiating a surface of a metal member with a laser beam while supplying a weld metal powder, and performing overlay welding on the surface of the metal member, and repeatedly performing a weld bead formation step of melting and solidifying the weld metal powder with the laser beam to form a plurality of weld beads on the surface of the metal member. Each of the plurality of weld beads has one portion in a width direction overlapping each other. In the overlay welding method, in a case of forming an adjacent weld bead, which is a weld bead adjacent to a previously formed weld bead, an energy density of the laser beam is adjusted to be higher at a portion of the adjacent weld bead overlapping the previously formed weld bead than at a portion not overlapping the previously formed weld bead. |
