Abstract: The present invention relates to a method for joining a plated steel sheet, in which at least one of a first steel sheet and a second steel sheet is a plated steel sheet, and the first and second steel sheets overlapped with each other are subjected to an arc spot welding. The method includes press-working the first steel sheet into a desired shape and at the same time forming a linear groove on an overlapping surface with the second steel sheet of the first steel sheet, overlapping the first and second steel sheets, and setting a welding torch with the groove as a target position, and performing the arc spot welding so as to overlap the groove when viewed from a direction perpendicular to the overlapping surface.

Abstract: This arc spot welding method for dissimilar materials joins a steel upper plate and a non-ferrous metal lower plate. The upper plate has a flat plate-like base part and an upright wall part erected on the base part. The base part has a through-hole. The arc spot welding method for dissimilar materials includes superposing the base part on the lower plate so that the lower plate faces the base part via the through-hole; and arc-welding the base part and the lower plate by filling the through-hole with a molten weld metal at a position, which is a target position, offset in the direction opposite the upright wall part from the center of the through-hole.

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.
