METHOD FOR MANUFACTURING MULTI-LAYER MOLDED ARTICLE

WIPO Patent Application WO/2022/038960

A1

According to the present invention, an internal molding step for molding an internal molded part inside a frame includes: a pre-measurement process for measuring the shape of a substrate on which a weld bead layer is to be laminated; a deviation quantity calculation process for generating a real measurement profile of the substrate from real measurement values of the measured shape of the substrate, determining a plan profile of the substrate from a lamination plan, and calculating a deviation quantity of the real measurement profile from the plan profile; and a pre-correction process for correcting a welding condition of a weld bead constituting the weld bead layer in the lamination plan so as to reduce the deviation quantity when laminating the weld bead layer on the substrate.
