Process parameters optimization of pulsed laser welding of 6061 aluminum alloy based on SPA

  • 摘要: 以激光峰值功率、焊接速度、脉冲宽度、离焦量为优化工艺参数,以焊接接头的抗拉强度、断后伸长率、焊缝熔深、焊缝宽度为综合优化工艺目标,运用正交试验与集对分析相结合的方法对6061铝合金脉冲激光焊接工艺进行了多目标优化. 通过正交试验获得数据样本,利用集对分析法对数据分析以实现工艺参数的优化. 首先确定单工艺目标与理想解的同一度、对立度、贴近度,然后以单工艺目标贴近度的权重和表示综合工艺目标的贴近度. 最后根据不同工艺参数、不同工艺水平的综合工艺目标的平均贴近度确定最佳工艺. 优化结果为:激光功率3.5 kW、焊接速度2.4 m/min、脉冲宽度4.0 ms、离焦量-1 mm.
    Abstract: Taking laser peak power, welding speed, pulse width and defocusing quantity as optimization process parameters, the tensile strength, elongation, welding depth and weld width of the welded joint are optimized. The pulse laser welding process parameters optimization of 6061 aluminum alloy of multi-objective is carried out by combining orthogonal test and the analysis theory. The data samples are obtained by orthogonal test, and the data analysis is used to optimize the process parameters by the set pair analysis method. First, we determine the identity degree, degree of opposites and closeness degree of single process objectives between ideal solutions. Then we use the weight sum of nearness of single process objectives to represent the closeness of comprehensive process objective. Finally, the best process parameters are determined according to the average closeness of the comprehensive process objective of the process parameters in different process levels. The optimized results are as follows: laser power 3.5 kW, welding speed 2.4 m/min, pulse width 4.0 m/s, defocusing-1 mm.
