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。 By studying the static strength and fatigue strength of the multi-spot welding lap-joint, the influence of the spot-pitch on the strength is discussed, and the stress state near the spot in the plate is analyzed by the elastic mechanics model, which can correspond well with the experimental results.
