Effects of welding parameters on the quality of resistance spot welded SAE 1010 steel sheet

Resistance spot welding has been commonly used in the automotive industry for joining body sheet components and it is particularly well suited for uncoated low carbon steels. The present paper reports experimental investigations on the spot welding of uncoated 1010 steel sheets. Experiments were carried out using different welding parameters, electrode tip radius and sheet thicknesses. Then, the results are used to discuss the effect of welding conditions on surface appearance, weld size, tensile shear strength, depth of fusion and heat affected zone.
