摘要
管道焊前对管端进行耐蚀金属粉末喷焊防腐，然后采用与之匹配的耐蚀焊条打底焊，从而取代焊后焊接区内补口防腐的传统施工工艺。
After anticorrosion metal power spray welding was carried out for prevention of corrosion,the matched anticorrosion electrode is used to make backing weld.The new process can replace the traditional process with internal repaired mouth.
