Abstract
A method for manufacturing profiles formed so as to have different cross-sectional shapes in the height direction, in which a long-sized hoop of workpiece is indexed, a plurality of types of component members having outer contours corresponding to the respective cross-sectional shapes of the profile are formed in a plurality of stages and indexed in the state where the component members are replaced on the workpiece, and the component members are sequentially ejected from the workpiece, laminated into a profile in the final stage. Clearance holes passing through component members are provided simultaneously with the blanking of the component members, a plurality of the component members are laminated and welded together by applying a laser beam, and then another component member is laminated and pressed on the previously laminated and welded component members so that the clearance holes of the component member agree with the weld buildups on the previously laminated and welded component members, and welded together with the previously laminated and welded component members by applying a laser beam onto locations other than the clearance holes on the component member.
