摘要

In this study, the electric resistance spot welding process was applied to zinc-coated steel sheets used in automotive industry. Spot welding parameters namely, electrode form, electrode material, and electrode force were stayed constant, and welding current and welding time have been changed to detect the optimum welding parameters for maximum joint strength. Using 4, 5, 6, 7, and 8 kA welding currents and 5, 10, 15, 20, and 25 cycles welding times 1.0-1.0 mm sheets were spot welded to prepare samples. These spot-welded joints were then exposed to uniaxial tensile test, and tensile-shear and tensile-peel forces prior to breaking were determined. In addition, microstructures were detected by SEM and micro-hardness was measured from different regions of resistance spot-welded samples and recommendations showing the optimum welding parameters were given to users.
