A CAP TIP FOR SPOT WELDING

摘要

A cap tip for spot welding is disclosed. According to an embodiment of the present invention, the cap tip for spot welding comprises a pair of vibration welding guns facing each other on the basis of a welding unit of an overlapped panel. A welding tip reciprocally moving between the vibration welding guns is used for plastic flow to be generated. In a vibration spot welding device pressurizing the welding unit wherein plastic flow is generated to be connected, a cap tip for spot welding mounted on each front end of the vibration welding guns comprises: a body unit having an insertion hole wherein the welding tip is inserted to be moved; and a resistance reduction groove formed in a surface of the body unit which is in contact with the welding unit of a pair of panels.
