Abstract In the present work, experiments planned on the basis of statistical experimental design were carried out to study the influence of welding parameters (welding current, welding time, electrode force and sheet thickness) on the microhardness and strength of spot joints. Tensile shear strength, microhardness and nugget area of spot-welded commercial aluminium sheets (B.S. 1050) were measured, reported and correlated.
