Abstract: A target shape is set from a three-dimensional shape data of an additively-manufactured object, and the set target shape is sliced into a plurality of bead models having shapes corresponding to weld beads. A dripping amount of a filler metal to a lower layer during bead formation in a bead deposition portion where the sliced bead models overlap vertically is predicted according to welding conditions of the weld beads. A bead height of each bead model in the bead deposition portion is modified according to the predicted dripping amount. A deposition plan to manufacture the additively-manufactured object is created by using the plurality of bead models including the bead model with modified bead height.

Abstract: A strand production apparatus configured to produce a fiber reinforced resin strand having one or a plurality of fiber bundles including reinforcing fibers includes a twisting unit, a resin bath unit, and a winding unit. The twisting unit rotates the one or the plurality of fiber bundles around an axis of the one or the plurality of fiber bundles to form one or a plurality of twisted fiber bundles. In the resin bath unit, the one or the plurality of twisted fiber bundles are impregnated with a molten resin to form a fiber reinforced resin strand. The winding unit winds the fiber reinforced resin strand. The twisting unit is disposed on an upstream side of the resin bath unit in a conveying direction of the one or the plurality of fiber bundles.

Abstract: 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.

Abstract: An arc welding method includes welding a steel sheet while alternately switching feeding of a welding wire between forward feeding and backward feeding. The welding wire contains, in mass % with respect to a total mass to the welding wire, C: more than 0 and 0.30 or less, Si: 0.01 to 0.30, Mn: 0.5 to 2.5, S: 0.001 to 0.020, Ti: 0.05 to 0.30, and optional elements with the remainder being Fe and unavoidable impurities, and a value obtained by 2×[Ti]/[Si]−50×[S] is more than 1.0. The welding is performed by using a shielding gas containing CO2 gas in an amount of 80 vol. % or more with respect to a total volume of the shielding gas at a frequency of 40 Hz or more and 200 Hz or less, where one cycle for determining the frequency is one forward feeding and one backward feeding.
