Abstract The effect of Sm element on the microstructure, properties and hydrogen content of SAl4043 aluminum alloy welding wire was studied. The results show that the addition of Sm can refine the α-Al matrix and modify the eutectic silicon, the short-rod like and granular eutectic silicon are dispersedly distributed at the grain boundaries. The addition of Sm significantly improves the mechanical properties of the as-cast welding wire alloy because of the grain refinement and modiffication effect of Sm element. When 0.4wt% Sm is added, the alloy’s tensile strength reaches 140 MPa, and the elongation is 8.5%, which is 25% and 49% higher than that when no Sm is added. At the same time, the addition of Sm can significantly reduce the hydrogen content of the as-cast welding wire alloy, the minimum content reaches 0.15 mL/100 g Al when 0.4wt% Sm is added, compared with the alloy welding wire without Sm, the hydrogen content is reduced by 59%. The joint test indicates that the addition of Sm to the welding wire improves the mechanical properties and bending performance by reducing the weld porosity. When the content of Sm is 0.4wt%, the tensile strength and elongation reached 180.4 MPa and 10.2% respectively. At the same time, compared with that of Sm free one, the porosity of the weld is significantly reduced by 71%, only 0.16%.
