A custom Phased Array Ultrasonic Testing (PAUT) inspection tool, comprising both hardware and software, has been developed for the inspection of polyethylene (PE) pipe butt fusion joints. This system is designed for use by gas pipeline welding technicians with no prior knowledge of ultrasonic testing. The inspection technique was qualified using a set of butt fusion joint samples containing real, embedded defects. Scan results from these samples were then employed to train autoencoder models which are used for automated classification of butt fusion joints (flawed vs. unflawed) using the PAUT data. This presentation will cover the system's design, the inspection methodology, the AI training process, and the results of the qualification tests.
