Abstract
A stud welding method uses an inert mixed gas as arc shield in performing stud welding on a base metal, such as, vehicle body, by utilizing the stud, e.g. a T-stud, as an electrode, the stud serving as the positive pole while the base metal serves as the negative pole to thereby prevent formation of oxide film on the base metal surface during the welding, the inert mixed gas comprising carbon dioxide gas and argon gas.
