通过分析某钢管公司目前钢管超声波自动探伤设备的配置和钢管在扩径后发现的缺陷类型，找出了钢管扩径后超声波自动检测时偶尔发现焊缝横向缺陷的原因，提出了对现有钢管超声波自动探伤横向扫查系统的改造措施，即改变了横向探头及探头架的布置，增加了检测监视的通道数量。改造后的检测系统可靠性高，操作简便，稳定性好，探伤人员容易掌握。通过对该自动探伤横向扫查的改造，降低了钢管缺陷漏检的风险，提高了生产效率。

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.
