Ultrasonic pipe testing refers to a non-destructive testing method that uses ultrasound to inspect internal defects in metal components. Using an acoustic transducer to emit ultrasonic waves through a coupling agent to the surface of the component, the ultrasonic waves will have different reflected signals (echoes) when encountering different interfaces when propagating inside the component. By utilizing the time difference between different reflected signals transmitted to the probe, defects inside the component can be detected. The size, location, and approximate nature of defects can be determined based on the height and position of the echo signal displayed on the fluorescent screen. Ultrasonic testing is more sensitive to cracks, incomplete penetration, and incomplete fusion defects, but less sensitive to pores and slag inclusions. Ultrasonic testing has poor visualization and is not sensitive to near surface defects (known as blind spots in ultrasound).

Steel pipe weld flaw detection is divided into online flaw detection mode and offline flaw detection mode, and the equipment adopts beam type water film flaw detection. The system adopts the combination of computer control and real-time signal acquisition and processing technology, and uses multi-channel digital flaw detector with the support of high-speed computer to realize automatic detection of defects, automatic evaluation of defects, display and record (defect) echo amplitude, storage and printing detection data.
