对优化射线检测工艺的思考

The Considerations for the Optimized Radiographic-Examination Workmanship

结合标准和实例,评述有关优化焊缝射线照相无损检测工艺,提高窄小裂纹检出率的五个典型问题,并提出对现有标准中的一些主要技术参数需要重新审视和修改的建议。

Combining with standards and practical examples, five typical problems on optimizing NDT technique of weld radiography for increasing the detectability of small, narrow cracks are reviewed. It is suggested that the main related technique parameters in existing standards need to be reexamined and revised for optimizing conventional inspection.
