摘　　要：通过对凹底平车成形、组装焊接制造工艺和结构难点分析,确定了板材拼接采用焊条电弧焊,其它焊缝主要采用焊丝气体保护和自动化焊接设备及凹底架心盘预制12 mm上挠度和小底架心盘预制5 mm上挠度的制造工艺,并介绍了凹底架组成及小底架组成的焊接原则和顺序.实践证明,该工艺行之有效,凹底平车的组装质量和焊接质量均满足产品图纸及技术条件要求.The difficulties of assembly forming, welding manufacturing process and structure of depressed centre flat car are analyzed. It aslo formulates the manufacturing process of plate joining together by SMAW, MAG and automatic welding equipment,the concave bottom center plate is prefabricated 12 mm deflection, and small bot- tom center plate prefabricated 5 mm deflection. Principle of welding and order of small and concave chassis components are introduced as well. Practice has proved that the process is effective, the assembly quality and welding quality of depressed centre flat car all meet product design and technical requirements.
