ABSTRACT:
A method and apparatus for spot welding a wire to a terminal where the core wires of the wire are not crushed or frayed and where the tensile strength of the connecting portion is improved. In the method of connecting the terminal and wire by spot welding, a concave groove (27a) corresponding to a section of the wire is formed in advance in the top end of a wire-side electrode (27) of spot welding electrodes. An exposed core portion (1a) of the wire is laid on the inner surface of a wire connection portion (13a) of the terminal, a section of which has been worked into a U-shape. While this overlaid portion is held between a terminal-side electrode (25) and the concave groove (27a) of the wire-side electrode (27), a current is supplied thereto under pressure. The apparatus includes the two electrodes including the wire-side electrode having a concave portion in which the wire is received as well as the opposing terminal-side electrode.
