This study aims to determine the optimal parameters for cold metal transfer MIG welding of aluminum thin sheets. Starting from this perspective, the filler material of Al5Mg full wire type and a synergic regime of welding with a low linear energy were used. The characterization of welded joints was achieved by macro – microscopic analyses, mechanical tests (microhardness and tensile) aiming to lower the thermo - mechanically affected zone. The results highlight the major influence of the welding parameters over the weld bead geometry and tensile behaviour of the joint.
