Abstract: 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.

Abstract: A method for producing a resistance-welded member made of three or more sheets including a plated steel sheet includes: a main energizing by performing energization with a first current value while compressing the steel sheet with a first compressive force to form a nugget; a subsequent energizing by performing, after the main energizing, energization such that the current value gradually decreases from the first current value while compressing with a second compressive force greater than the first compressive force; and holding an electrode while maintaining the second compressive force after the subsequent energizing. The second compressive force and a total sheet thickness, compression rise delay time, and a downslope time and an electrode holding time satisfy respective predetermined conditions.
