PURPOSE: To provide the method and device which are capable of manufacturing high quality metallic parts and articles having undercut and an irregular shape by gradually build-up welding a material and which are usable together with existing equipment.
CONSTITUTION: A work face 4 is set to be movable two- or three-dimensionally as shown by the arrows x, y, z, and a welding head 10 is installed on the head 21 of CNC equipment 20. The head 21 is designed to hold a tool for cutting a workpiece of a machining table 22. A base material 3 is disposed or formed on the machining table 22 of the purpose of manufacturing an object. The table 22 or the head 21 is moved in a mode for delivering a metal to be welded, in relation to a predetermined pattern for forming each layer 2. Complementary materials adjacent to each layer are arranged by a spray gun 26.
