  • 摘要: 针对机器人铝合金冷金属过度焊接成形难度大及存在的问题和挑战,本论文系统性的对焊接工艺参数进行了综合优化研究。采用L9(3^4)正交实验法,设计了机器人焊接工艺参数实验,并利用极差分析和方差分析等方法对实验结果进行数据处理和分析,确立各个因素与焊接质量的内在影响权重关系,通过理论分析与实验,可得到如下结论:1)焊缝熔深和熔宽主要受送丝与焊接速度影响;2)焊接余高对机器人速度较为敏感;3)焊缝硬度主要取决于送丝速度及脉冲频率。基于上述结论,可切实解决面向不同应用场景下焊接零部件主要性能变化问题,提升焊接施工作业效率及质量。

     

    Abstract: This paper systematically investigates the comprehensive optimization of welding process parameters, targeting the difficulties and challenges associated with robot-assisted cold metal transfer welding of aluminum. Utilizing the L9(3^4) orthogonal array experimental method, we designed experiments for robotic welding process parameters. The experimental results were processed and analyzed using range analysis and variance analysis methods to establish the intrinsic impact weights of various factors on welding quality. Theoretical analysis and experimentation led to the following conclusions: 1)Weld penetration and width are primarily affected by wire feed and welding speed.2)Weld reinforcement height is particularly sensitive to the robot's speed.3)Weld hardness is mainly dependent on wire feed speed and pulse frequency.Based on these conclusions, effective solutions can be implemented to resolve the main performance variability issues of welded components in different application scenarios, thereby enhancing the efficiency and quality of welding operations.
