摘　　要：介绍埋地燃气聚乙烯管道电熔连接的概念、应用范围、注意事项、接头质量判断。分析解决电熔连接施工中观察孔溢料的问题。用实验方法对未能保持电熔连接焊接面的洁净导致电熔连接出现虚假焊进行了探讨。The concept, scope of application, matters needing attention and joint quality judgement in electrofusion welding of buried gas PE pipes are intro- duced. The problem of material overflow at the obser- vation hole in electrofusion welding operation is ana- lyzed and solved. The false electrofusion welding caused by unclean welding surface is discussed experi- mentally.
