摘　　要：CO2气体保护立向下焊技术在7mm以下厚度的构件角接焊中具有显著应用价值。基于CO2气体保护实芯焊丝立向下单道焊接在船舶上层建筑制造中的应用试验,探讨了此类焊缝的设计要点;分析了其焊接工艺参数的选取与匹配;并对该焊接方法中常见缺陷的预防提出了建议。CO2 shielded vertical down welding has a significant application value in fillet welding between steel members of thickness up to 7mm. Based on the application test of CO2 shielded vertical down single-pass welding during ship superstructure construction, this paper discusses the design key points of this type of welding seams, analyzes the selection and matching of welding parameters, and puts forward some suggestions to prevent the common defects in this welding method.
