摘　　要：在实验的基础上，就 5982铝合金板 (1 mm＋ 1 mm)直流点焊焊接参数对焊点性能的影响进行了分析研究。结果表明，焊接电流在一定范围内与焊点接头的拉剪载荷成正比，通电时间与电极压力都存在一个最佳范围，而加压方式对接头性能影响并不明显。Analysis and study were conducted for the effect of welding parameters of DC spot weld on weld performances for aluminium alloy sheet (1mm＋ 1mm)on the basis of experiment. It is shown by test results that the welding current is directively proportional to the tensile shearing load of weld connector within a certain range, an optimum range is existed for both electrifying time and electrode pressure, while the pressure application mode has no marked effect on weld performance.
