摘要

介绍了我国核岛规范1、2、3级机械设备用焊接工艺评定存在的两份标准,对其中的耐蚀堆焊工艺评定要求从焊接变素和检验项目两个方面进行了比较与分析,找出差异,为今后解决差异创造条件,以争取最终获得融合统一的核岛机械设备焊接工艺评定标准。

Abstract

The situation of two Chinese criterions for welding procedure qualification on the class 1,2,3 components are introduced. By comparing and analyzing the welding procedure qualification for corrosion resistant surfacing from the aspects of welding parameters and examination,the differences are found,which provides some reference and guide to solve them and finally obtain the unified welding procedure qualification criterions for the future.
