摘要：The lap joint characteristics of laser-TIG-adhesive hybrid welding of AZ61 magnesium alloy to Q235 steel are examined. The microstructures and elemental distribution of the Mg-steel dissimilar laser-arc-adhesive hybrid welding joint are investigated. A certain concentration of Mg element is found in the Ni-Fe solid solution. The metallurgical combination is attributed to the formation of a 3 mu m to 5 mu m thick Mg-Ni-Fe diffuse transition layer caused by adhesive addition. A metallurgical combination mode is revealed at the Mg-Ni-Fe interface in the Mg-steel laser-TIG-adhesive welding joint, which demonstrate the combined effect of the polymer and metals. The mechanical property of linear load is 3.50 kN/cm with the adhesive cured.
