摘要

铝合金焊接时容易产生气孔，严重影响焊缝的力学性能。激光摆动焊接工艺可以显著降低铝合金焊接过程中的气孔率，提高接头拉伸强度，但其工艺参数繁多且互相影响，很难直接对工艺参数进行优化。因此设计了18组正交试验，通过极差分析研究了不同工艺参数对气孔率的影响程度，并通过正交优化设计对工艺参数进行优化。通过不同的学习算法建立BP神经网络，结果表明使用BR算法的模型均方误差最小，预测性能最好。采用遗传算法结合BP神经网络对焊缝性能和焊接效率进行多目标优化，获得的焊缝拉伸强度相比正交优化所得焊缝提升了3.02%，焊接效率提升了18.3%。BP神经网络-遗传算法组合模型可在保证焊接性能的同时提高焊接效率。

Abstract

Aluminum alloys tend to produce pores during welding

which critically affects the mechanical properties of the weld. The laser oscillating welding can significantly reduce the porosity of aluminum alloy welding. However

it is very difficult to figure out and optimize the welding parameters since they are in a complex relationship. To study and figure out the influence of different parameters on porosity

18 sets of orthogonal experiments are designed followed by the analysis of variance. In addition

the welding parameters are optimized by the analysis of variance. The multi-objective optimization of weld performance and welding efficiency are carried out by using genetic algorithm combined with BP neural network. The tensile strength of the weld optimized by genetic algorithm is increased by 3.02% and the welding efficiency is increased by 18.3% compared with the orthogonal optimization. Therefore

the combined model of BP neural network and genetic algorithm can improve welding efficiency while ensuring welding performance.
