摘　　要：针对汽车刹车接头传统钎焊工艺效率低下、焊接质量得不到保证的现状,设计了一种汽车刹车接头激光自动焊接系统。根据焊接工艺以及设备的组成结构,分析了影响汽车刹车接头质量的主要工艺参数。采用Box-Behnken设计方法,建立焊接质量与激光焊接功率、焊接速度和离焦量等主要焊接工艺参数的数学模型,分析各个工艺参数对焊接质量影响的显著性。根据焊接强度指标,优选汽车刹车接头激光自动焊接系统的最佳工艺参数,并通过焊接试验进行验证。研究结果表明,该自动焊接系统对相关汽车刹车接头厂家提高工件质量和生产效率具有积极意义,并且可以推广到同类环形零部件激光焊接的研究与应用中。In view of the low efficiency of the traditional brazing process of automobile brake joints and the insufficient welding quality,a laser automatic welding system for automobile brake joints was designed. According to the welding process and the structure of the equipment, the main process parameters that affect the quality of automobile brake joints were analyzed. The Box-Behnken design method was used to establish a mathematical model of welding quality and laser welding power, welding speed and defocusing parameters and other main welding process parameters, and analyze the significance of the impact of each process parameter on welding quality.According to the welding strength index, the best process parameters of the laser automatic welding system for automobile brake joints were optimized and verified by welding tests. The research results show that the automatic welding system has guiding significance for related automobile brake joint manufacturers to improve the quality and production efficiency of the workpiece, and can also be extended to the research and application of laser welding of similar ring parts.
