Abstract: A method for manufacturing a laminated body includes: laminating an electromagnetic steel plate to form the laminated body; performing an annealing process on the laminated body; acquiring a before-annealing lamination thickness information on a thickness of the laminated body before performing the annealing process on the laminated body; and when the before-annealing lamination thickness information does not satisfy a before-annealing criterion which is predetermined, adjusting a lamination condition of the electromagnetic steel plate such that the before-annealing lamination thickness information satisfies the before-annealing criterion.

Abstract: A method of manufacturing a metal product comprise forming a base region on a surface of a metal member by repeatedly scanning along a predetermined first direction while irradiating the surface of the metal member with a base laser beam over a first set of rows. The method further comprises forming a marking by repeatedly scanning along a predetermined second direction while irradiating the surface of the metal member with a marking laser beam over a second set of rows. The second direction is different from the first direction. An identification code having a predetermined pattern comprises a combination of the base region and the marking.

Abstract: A method of manufacturing a metal product includes forming a first identification code onto a surface of a metal member with a laser beam, the first identification code being readable under a first reading condition, and heating the metal member on which the identification code is formed. The method further includes reading the first identification code with a reading device, and forming a second identification code onto the surface of the metal member subsequent to the heating with a laser beam based on the first identification code which is read with the reading device. The second identification code is readable under a second reading condition different from the first reading condition.
