First Claim
Patent Images
1. A joining method comprising:
- overlaying, on a first component made of a steel material, a second component made of a material different from the steel material;
pushing a tapered distal end of a button component in the second component from an obverse surface side of the second component and abutting the distal end against the first component by applying a first pressure to the button component without heating, the button component including a head portion and a shaft portion, the shaft portion including one end connected to the head portion, and the other end that forms the distal end, and the button component being made of steel including a cross section being parallel to an axial direction and in a substantially T shape; and
welding the distal end of the button component and the first component by resistance spot welding while applying a second pressure lower than the first pressure to the button component in a state in which the distal end abuts against the first component.

Abstract
An aluminum plate (103) is overlaid on a steel plate (102). A distal end (113) of a button component (101) is pushed in from the obverse surface side of the aluminum plate (103), and the distal end (113) is abutted against the steel plate (102) by applying a first pressure to the button component (101) made of steel without heating. The distal end (113) of the button component (101) and the steel plate (102) are welded by resistance spot welding while applying a second pressure lower than the first pressure to the button component (101).
