摘　　要：通过研究多点焊搭接构件的静强度与疲劳强度，探讨了焊点间距对强度的影响，并且用弹性力学模型分析了板中焊点附近的应力状态，与实验结果能较好地对应。The paper studied the influence of the distance between weld spots on static and fatigue strength by the experiments of multi spot welded plate,and we got the stress distribution around the weld spots by our mechanical model,it tallied with our experiment date.
