Japanese Patent JP7381422

B2

To provide a manufacturing method of a molded article capable of manufacturing efficiently a high quality molded article, forming weld beads accurately around a shaft body while inhibiting generation of non-welded portion and provide the molded article.SOLUTION: A manufacturing method of a molded article comprises: a wall portion molding step of molding a plurality of wall portions 53 in a circumferential direction of a shaft body 51 at intervals in an axial direction; and an inside molding step of forming weld beads B2 which are each wider than the wall portion 53 in the circumferential direction of the shaft body 51 within a filling range FR between the wall portions 53 while sequentially arranging the weld beads adjacently toward an axial direction of the shaft body 51 to fill the filling range FR with the weld beads B2. The inside molding step performs a trajectory changing process of directing a trajectory of the weld bead B2 toward the axial direction of the shaft body 51 at a position the weld bead B2 being formed toward one side of the circumferential direction of the shaft body 51 contacts the weld bead B2 previously formed, and, further, directing the trajectory of the weld bead toward the one side of the circumferential direction of the shaft body 51 at a position adjacent to the existing weld bead B2 in the axial direction of the shaft body 51.SELECTED DRAWING: Figure 3D
