Abstract
A metal laminating and molding method molds a 3-dimensional molded object formed by sequentially laminating a plurality of metal layers. The metal laminating and molding method is accomplished by repeatedly performing a unit process including a metal layer laminating process of laminating the metal layer constituted by welding beads formed through arc welding and a removal process of removing impurities from a surface of the metal layer laminated in the metal layer laminating process. When the unit process is repeated, the metal layer laminating process is performed again such that a new metal layer is laminated on the surface of the metal layer from which impurities have been removed in the removal process.
