ABSTRACT:
An apparatus and a method are disclosed for manufacturing a laminated product. The method includes the steps of punching out components from a plate with a punch and a die and accommodating the punched components in a component accommodating cylindrical member, emitting a laser beam with a laser beam emitting device to a portion between adjacent components. The components are laminated, one on the other, in the component accommodating cylindrical member. The laser beam passes through a beam passage hole formed in the peripheral surface of the component accommodating cylindrical member. The beam passage hole is located through a predetermined rotational angle range of the component accommodating cylindrical member so as to weld the components to manufacture the laminated product. Also, the die and the component accommodating cylindrical member are rotated by a predetermined angle during the welding operation.
