摘　　要：本文首先将PE管的热熔焊接与金属焊接进行了区别,并介绍了其工艺过程;其次对PE管热熔对接接头的断口特征进行了分类,并分析了PE管热熔对接接头中可能产生的缺陷,虚(焊)粘、假(焊)粘是PE管存在的主要缺陷,对对接接头的强度影响较大。可以采取超声波检测方法控制PE管热熔(焊接)粘接接头的内部质量,以保证工程应用安全。In this article,the distinction between the fusion welding and melt welding of the PE pipe was given,whose process was also introduced.Then the fracture characteristics of PE pipe butt joints were classified,and it gave an analysis of the possible defects of PE pipe butt fusion joints,finding that,virtual（welding） stick and false（welding） of PE pipe sticking were major defects which had influence on the impact of butt joints.Ultrasonic testing could be used to take control of PE pipe internal quality of fusion（welding） adhesive joints in order to ensure the safety of engineering application.
