Abstract: Disclosed is a welding-type fixing cap used for attachment to both ends of a cylindrical battery composed of metal materials. The welding-type fixing cap comprises a ring-shaped side wall; a visor surface extending outwards from one end of the side wall; a welding lug formed on the visor surface, wherein the welding lug is meltable in a welding process; a cutting hole formed in the side wall, wherein the cutting hole is dimensioned and configured for discharging gas. The welding lug is positioned distal to the side wall and proximal to a cutting hole. The welding-type fixing cap has a sufficient strength, while recuding electric current leakage during a contact-resistance welding.
