Abstract
A method of resistance spot welding that enables an improvement of a weld strength of steel plates having different plate thicknesses while inhibiting generation of spatters is provided. One aspect of the present disclosure is the method of resistance spot welding, the method including welding a workpiece made of layered steel plates with a resistance spot welding apparatus. The resistance spot welding apparatus includes a first electrode configured to contact a first steel plate among the steel plates, and a second electrode configured to contact, among the steel plates, a second steel plate that is thinner than the first steel plate, and the second electrode being arranged such that the workpiece is interposed between the first electrode and the second electrode. The welding includes welding while moving the second electrode relative to the first electrode in a direction parallel with a plate surface of the second steel plate.
