小径管焊接接头伽玛射线检测专用工装设计与应用

摘要

The fix of gamma ray source in the process of radiographic testing of commonly used small butt joint has disadvantages.Through analysis and research,a specialized tool set was designed for the gamma radiation detection of small tube butt joint,which solved the problem of how to fix the ray source in a fast,accurate,stable manner and to maintain appropriate focus,thus improving the work efficiency and work safety.%常用小径管焊接接头伽玛射线检测过程中,射线源存在着固定不方便、不牢靠,安装后稳定性不好等问题,设计出小径管焊接接头伽玛射线检测专用工装并应用于工程实践.结果表明,该工装可快捷、准确、稳固地固定射线源并能保持合适焦距,提高了工作效率及工作安全性.
