The aim of this study was to optimize the parameters of spot welding of 6061 Al alloy. Spot welding of 6061 Al alloy of 2 mm thickness were carried out by orthogonal experiment, the analysis of variance and the performance test were conducted. The optimal scheme of variance was the current of 22 kA, the electrode pressure of 0. 15 MPa and the welding time of 15 frequencies. The maximum tensile force of joints under the optimal scheme of variance was 5. 444 kN, increased by 25. 5% compared with the maximum tensile force in the orthogonal experiment. The optimum parameters of spot welding for 6061Al alloy was the current of 22 kA, the electrode pressure of 0. 20 MPa and the welding time of 11 fre-quencies. Under these parameters, the tensile strength of joints was 6. 262 kN, increased by 44. 35% compared with the maximum tensile force in the orthogonal experiment.
