Abstract
Through analysis on the configuration of steel pipe automatic ultrasonic flaw detection and defects type after pipe expansion in some steel pipe company,it got the reason of weld transverse defects occasionally found out during automatic ultrasonic inspection after pipe expansion,and put forward the reform measures of the existing automatic ultrasonic inspection transverse scanning. That is varying the arrangement of transverse probes and probe frame,adding monitor channel quantity. After reform,the testing system is with high reliability,simple operation,good stability,and the inspection personnel easy to master. The reforms decrease the risk of steel pipe missing detection,and enhance the productivity.关键词
