汽车生产用激光钎焊系统设计

随着汽车工业的发展以及人们需求的不断提高,节能、安全、环保成为汽车技术的三大主题,而激光加工工艺的发展对解决汽车节能、安全和环保具有重要的意义。激光以其光束能量密度高、热影响区域小、焊接速度快、深宽比大和变形小等优点,在白车身制造领域得到广泛应用。近几年,伴随着我国逐渐迈向汽车产销大国的步伐,激光焊接这一前沿技术已相继出现在国内主流汽车企业的生产线上,而其中又以激光钎焊的应用最为广泛。在此以某量产车型的行李箱盖激光钎焊为例,结合其工艺特点,系统介绍激光钎焊系统的设计方案,并着重分析了主要核心设备的技术特点。

Design of laser brazing system applied in automobile

As the development of automobile industry and improvement of people's requirement,energy saving,safety,environment protection become the three primary topics of automobile technology.At meantime,the improvement of laser process technology have important signification for energy saving,safety,environment protection.Laser welding depend on high density of energy,small heated effect area,high welding speed,big depth breadth ratio of seam,less distortion and so on,was widely applied in the manufacture of automo...
