This article describes the Total Focusing Method applied to pipeline defect imaging. Through the acquisition and processing of phased array time-domain signals, qualitative and quantitative imaging of pipeline defect parts is achieved. As a phased array ultrasonic post-processing method, this technology has high imaging resolution and can improve the imaging characteristics of pipeline defects. It is currently gradually developing and applied to the medical field and industrial non-destructive testing.
