摘要
Abstract
A method is introduced for detecting socket weld fillets using ultrasonic phased array technology,which addresses the issue of structural echo interference in the analysis of defects during socket weld fillet inspection.The approach requires the use of a dual-axis encoder for scanning,with one axis rotating around the axis of the branch pipe,and the other axis controlling the distance between the probe on the main pipe and the axis of the branch pipe.During the scanning process,the probe moves around the branch pipe on the main pipe,always pointing towards the axis of the branch pipe.For each scanning cross-section,a three-dimensional Cartesian coordinate system is established in the current scanning cross-section,with the axis of the branch pipe as the y-axis,and the intersection of the axes of the main pipe and the branch pipe as the origin.The intersecting line analysis equations between the current scanning cross-section and the socket weld fillet workpiece are constructed separately.According to the intersecting line analysis equations,the intersecting lines between the current scanning cross-section and the socket weld fillet workpiece are plotted on each sector scan image.By referencing these intersecting lines,inspection engineers can more accurately analyze the defects in the socket weld fillet workpiece,eliminating structural echo interference,effectively solving the problem of difficulty in distinguishing structural echoes during the inspection process of socket weld fillets.关键词
