摘要：
A method of spot welding aluminum alloy workpieces having electrical conductivity of 18.about.57% IACS and Vickers hardness of 26.about.200 is disclosed. The aluminum alloy workpieces are spot welded by a pair of welding electrodes having an electrical conductivity of not less than 92% IACS and a Vickers hardness of 50.about.130. The differences of the electrical conductivity and Vickers hardness between the welding electrodes and the aluminum alloy workpieces are in a range of 41.about.87% IACS and not larger than 99, respectively.
