    摘要： In a series spot welding method, spherical leading edge portions (26a,27a) of pressed electrode tips (26,27) crush bearing surfaces (30a) that are one stage higher than a general portion (35). Thereby, the bearing surfaces (30a) are first deformed into a spherical shape. The bearing surfaces (30a) thus deformed into the spherical shape are then brought into spot contact with a second steel plate (Wb). Thus, the bearing surfaces (30a) thus deformed into the spherical shape form a conduction path narrowed down to a spot, between a first steel plate (Wa) and the secong steel plate (Wb). Therefore, the density of welding current flowing through the conduction path can be enhanced, and a nugget of sufficient size can be created between the first and second steel plates (Wa,Wb).
