摘要
为适应新车型天窗结构开发,解决传统弧焊焊接时容易造成的焊接变形大、焊缝气孔、裂纹等缺陷,在新车型全景天窗顶盖结构开发中采取CMT焊接工艺。文章重点针对CMT焊接原理进行分析,通过现场实践验证工艺焊接参数对焊接质量的影响,设置合理焊接参数,满足焊接质量要求。
In order to adapt to the development of new model skylight structure,to solve the defects such as large welding deformation,weld porosity,crack and so on,which are easily caused by traditional arc welding,CMT welding technology is adopted in the development of new panoramic roof structure.This paper focuses on the analysis of CMT welding principle,the influence of welding parameters on welding quality is verified through field practice,and reasonable welding parameters are set to meet the requirements of welding quality.
