摘要： A flux cored wire which exhibits excellent welding workability during gas-shielded arc welding, while enabling the achievement of a welded metal that has excellent tensile strength and toughness at low temperatures. The wire is obtained by filling a sheath with a flux and is adequately controlled with respect to the corresponding chemical components, while having a θ of from 10.0 to 30.0 as calculated by the mathematical formula (I): θ=4.1×α−3.2×γ−32.3. The respective contents, in mass %, of Si, Cr, Mo, Ti, C, N, Mn, Cu and Ni, relative to the total mass of the wire, are respectively represented by [Si], [Cr], [Mo], [Ti], [C], [N], [Mn], [Cu] and [Ni], α=0.02×[Si]+[Cr]+1.20×[Mo]+0.3×[Ti]+0.30 and γ=24×[C]+28×[N]+0.25×[Mn]+0.5/[Cu]+1.10×[Ni].

摘要： A bumper system includes a rear wall of a bumper beam provided with hole portions, and a bumper stay including tubular portions extending in the longitudinal direction, the tubular portions being inserted into the hole portions and joined to the hole portions by pipe expansion joining. The bumper stay includes a pulling-out obstructing portion protruding from the outer surfaces of the tubular portions in a cross section perpendicular to the longitudinal direction. The pulling-out obstructing portion abuts on the rear wall of the bumper beam in the direction in which the bumper stay is pulled out from the hole portions.

摘要： A defect occurrence prediction method uses a mathematical model to associate input information, which includes various items, namely the material of a built object, welding conditions for welding beads, and a welding track; and output information, which includes defect information regarding the built object where additive manufacturing has been performed under the conditions in the input information. This mathematical model is used to create a database, and the defect information regarding the built object is found by searching the database, and the defect information is then presented. Each item of the input information includes a plurality of input subitems that are mutually different. The output information includes a plurality of individual defect information items which correspond respectively to the input subitems. When the mathematical model is generated, the respective input subitems of the input information are associated with the individual defect information items via the mathematical model.
