Abstract：This article introduces the principle of polyethylene pipe hot melt welding and common defects of polyethylene pipe hot

melt joints. It analyzes in detail several non-destructive testing methods for polyethylene gas pipe hot melt joints: ultrasonic testing

(conventional ultrasonic testing, ultrasonic phased array testing, nonlinear ultrasonic testing technology), terahertz testing, X-ray

testing, and infrared thermal imaging. It discusses the theories and advantages and disadvantages of various non-destructive testing

technologies, Summarized the latest research progress.
