长期以来 ,各车辆段对上下心盘的修复一直沿用手工电弧堆焊工艺 ,这种工艺劳动强度大 ,工作效率低 ,堆焊质量难以保证 ,而且环境污染严重 ,修车成本高 ,因此 ,研制新型的符合心盘焊接工艺的心盘焊接设备具有广泛的社会效益和经济效益。图 1 XP— 50 0型货车心盘焊接设备结构
For a long time, the repairing of the upper and lower mandrels has been followed by manual arc welding process, which has the advantages of labor intensity, low work efficiency, hard quality of surfacing, serious environmental pollution and high repair costs. Therefore, A new type of heart plate welding process of the heart plate welding equipment has a wide range of social and economic benefits.
