1. 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, the first steel sheet having a first surface and a second surface, and the first and second steel sheets overlapped with each other in such a manner that the second surface of the first steel sheet facing the second steel sheet are subjected to an arc spot welding, the method comprising:
press-working the first steel sheet into a desired shape and at the same time forming a linear groove on at least one of the first surface and the second surface of the first steel sheet corresponding to an overlapping part with the second steel sheet;
overlapping the first and second steel sheets; and
placing a welding torch directly over the first surface of the first steel sheet 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.
