摘要
介绍了蒸汽发生器用套管式换热器中套管对接焊缝的X射线检测工艺,进行了底片黑度差和检测结果分析,通过控制透照参数,透照布置来控制黑度范围。实践表明:进一步改进和完善工艺可以把底片质量控制得更好。
What introduced in this paper is the casing type heat exchanger for steam generator,casing butt weld X-ray detection technology,X-ray photography analysis,and the photography density difference,which can be controlled by the control of photography variables and its arrangement.Further improvement and perfection of the production process can control the quality of the negative better.
