摘要
针对轨道车辆CO2 冷媒空调不锈钢管路系统焊接的工艺难点,应用不锈钢管TIG自动焊工艺来解决CO2 空调不锈钢管焊接可行性问题.总结了不锈钢管TIG自动焊焊接工艺参数设定依据,通过该方式确定的工艺参数可以得到高质量的焊接接头.同时介绍轨道车辆CO2 冷媒空调管路系统焊接后密封性检测要求,为该类空调的系统设计、施工和密封性检测提供参考.
Abstract
Focused on the technical difficulties in the stainless steels pipe system welding of CO2 refrigerant air condi-tioning in railway vehicles,we applied TIG automatic welding process of stainless steels pipe to tackle the feasibility of stainless steels pipe welding of CO2 air conditioners.It was summarized that the process parameters setting basis of TIG au-tomatic welding process of stainless steels pipe,which could obtain the high-quality welding joints with the process parame-ters of this way.Meanwhile,the requirements for sealing test of CO2 refrigerant air conditioning pipeline system in railway vehicles after welding were introduced,which provided reference for system design,construction and sealing test for this type of air conditioners.
