Effect of process variables (electrode pressure, holding time, welding current, and welding time) on low-carbon steel resistance spot welds performance has been investigated in this paper. Failure mode, peak load, and maximum energy obtained in tensile-shear test have been used to describe spot welds performance. Excessive electrode pressure can reduce both peak load and maximum energy, considerably. Holding time does not significantly affect peak load and maximum energy for investigated
more » ... l. Increasing welding time and welding current to some extent increases both peak load and maximum energy. However, excessive welding time and welding current not only do not increase weld nugget size and peak load, but also decrease maximum energy.
