An investigation on spot welding for galvanized steel sheets of 0.4,0.6,0.7 and 1.0mm thickness is reported in this paper. Tension shear and cross tension strengthes are tested, making one of four spot welding conditions i.e., current, time, pressure and spherical radius of electrode tip, variable and the other three constant, showing effects of these welding conditions by curves. Experiment on weld consistency, surface conditions and microscopic structures of the weld nugget are also explained. Zinc is not found in the weld nugget by spectrographic analysis.
