To investigate the properties of laser spiral spot welded joints of galvanized steel sheets with different spiral trajectory diameters, experiments were carried out on two lap joint configurations: a 0.7 mm and 2.5 mm large thickness ratio lap joint of galvanized steel sheets, and a three-layer thin galvanized steel sheet assembly with a thickness of 0.7 mm. For each configuration, three groups of tests were designed, including resistance spot welding and laser spiral spot welding with spiral trajectory diameters of 6 mm and 8 mm, respectively. After welding, the welded joints were analyzed from the perspectives of macro-appearance, metallographic microstructure and shear mechanical properties, so as to study the differences of laser spiral spot welded joints under different spiral diameters. The results show that the surface quality of laser spiral spot welded joints is relatively poor, and there is no significant difference in the surface quality of laser spot welded joints with different spiral trajectory diameters. However, the shear resistance and energy absorption capacity of the welded joints are significantly enhanced with the increase of laser spiral trajectory diameter, which proves that the spiral trajectory diameter has a great influence on the mechanical properties of the welded joints. Compared with resistance spot welding, laser spiral spot welding is superior in plastic deformation capacity and energy absorption performance.

为研究镀锌钢板不同螺旋轨迹直径下激光螺旋点焊接头性能，分别设置厚度为0.7 mm与2.5 mm的大料厚比镀锌板搭接组合和0.7 mm的3层镀锌薄板组合进行试验。每种搭接组合分别设置电阻点焊及螺旋轨迹直径分别为6 mm、8 mm的螺旋点焊3组试验。焊接完成后，从各焊接接头的外观、金相组织、抗剪切力学性能等方面进行分析，研究不同螺旋轨迹直径下激光螺旋点焊焊点接头的差异性。试验表明，激光螺旋点焊的外观质量较差，不同螺旋轨迹直径的激光焊点接头外观质量差异性不大；但随着激光螺旋轨迹直径增大，焊点接头的抗剪切力与吸能效果有明显增强，可见，螺旋轨迹直径对焊点接头的力学性能有较大的影响。对比电阻点焊，激光螺旋点焊在塑性变形能力及吸能性能上更优秀。
