Aluminum alloy 6063-T5 and AISI SAE 1020 were obtained with dissimilar welded joints by friction stir welding in 2.0 mm thick sheet. The aim was to evaluate the effect of welding parameters to obtain Al-steel welds. Joints were evaluated according to surface quality and depth of the welded region. It was determined that besides the rotational (ω) and forward (ν) speeds, the offset and the tool penetration are key parameters because they define the heat input and therefore the adherence of aluminum in the tool, the surface quality and defect formation along the joint line.
