Developing a scientific relationship between non-destructive testing ("NDT"), manufacturing acceptance levels and integrity requirements for pressure equipment welds

压力设备焊接验收涉及三个工程领域：制造验收标准、无损检测和结构完整性分析。从历史上看，这些领域中的每一个都是由不同的研究小组单独开发的。近年来，随着对失效风险的新要求、无损检测技术的革命和结构完整性分析的进步，这些发展加快了。因此，现在各种要求之间存在很大的不一致之处，这导致了工业界的严重纠纷。 该项目旨在重新定义各领域之间的适当关系，并为标准制定制定一条科学和合理的途径。

The acceptance of pressure equipment welds involves the interplay of three engineering fields: manufacturing acceptance standards, non-destructive testing and structural integrity analysis. Historically each of these fields has been developed separately by different research groups. In recent years these developments have accelerated with new demands on failure risk, a revolution in NDT techniques and advances in structural integrity analysis. As a result there are now large inconsistencies between the various requirements which lead to serious disputes in industry. This project seeks to redefine the appropriate relationship between the fields and develop a scientific and logical pathway for standards development.
