Abstract

Provided is a projection bolt welding method, which involves welding a projection bolt to a steel sheet component by electric resistance welding. The projection bolt includes a shank, a circular enlarged diameter portion, and a welding projection including an initial fusion portion with a tapered portion and a main fusion portion. A ratio of a volume of the initial fusion portion to a volume of a portion of the steel sheet component having the same diameter as a diameter of the initial fusion portion is selected, or a ratio of a circular area of the initial fusion portion to a sheet thickness of the steel sheet component is selected.
