摘要： The present invention has: a setting step for setting lamination patterns respectively for an outer edge portion and an inner portion of a shape indicated by shaping data; and an adjustment step for adjusting a forming sequence such that, during manufacturing when the lamination patterns are used to laminate and thereby form the outer edge portion and the inner portion, the height of the already laminated outer edge portion is higher than the height of the inner portion that is being newly laminated. In the lamination patterns, the orientation of the heat source when a region positioned at a boundary with the outer edge portion is formed is set so as to be inclined at a prescribed angle toward the outer edge portion in a plan perpendicular to a movement direction of the heat source.

摘要： A flux-cored wire comprising a flux which is a core and a hoop which is an outer skin or sheath is described. The flux includes a strong deoxidizing metal element containing Mg and Al, and a fluoride powder. At least 60 mass % of a strong deoxidizing metal powder related to the strong deoxidizing metal element has a grain size of at most 150 μm. At least 60 mass % of the fluoride powder has a grain size of at most 75 μm. The flux is present at a concentration of 10-30 mass % relative to a total mass of the flux-cored wire. The flux-cored wire also requires a specific composition of elements.
