Abstract: A weldment manufacturing method includes a recess forming step of forming recesses on a first target member and a second target member, the recesses delineating holes each of which spans across the first target member and the second target member and that are arranged along a boundary between the first target member and the second target member when the first and second target members that are the objects to be welded together are brought into abutment against each other; an abutting step of bringing the first and second target members into abutment against each other by aligning the recesses so that the recesses delineate the respective holes; and a welding step of placing filler material in the respective holes irradiating and scanning the filler material with the laser to cause the filler material to melt so as to fill the holes with the molten filler material.

Abstract: A weldment manufacturing method includes drilling that forms a hole on a workpiece, feeding a filler material to the hole and putting the filler material on a bottom of the hole, and melting the filler material by emitting a laser beam to the hole while scanning with the laser beam, so as to fill the hole with the melted filler material. By repeating the feeding and the melting, a weld repairing portion filling the hole is formed.

Abstract: A modeling system (control device) includes a control unit that controls a modeling means to form each of stacked modeling layers, based on modeling data representing a three-dimensional model object that is a modeling target by use of a plurality of modeling layers, a determination unit that measures and determines whether or not a measured value of a stacked height of the formed modeling layer is within a predetermined range set beforehand and including a stacked height of the modeling layer in the modeling data, and in a case where the formed modeling layer has a lacking part in which the stacked height is not within the predetermined range, a correction unit that performs correction modeling by forming a correction member in the lacking part such that the stacked height is within the predetermined range.
