燃气轮机燃烧室的射线工艺验证

RADIOGRAPHIC TESTING PROCESS TECHNIC VERIFICATION OF GAS TURBINE COMBUSTOR

铸件射线探伤与焊缝不完全相同,用于工艺验证的射线照相要求更高,结合铸件射线照相的一些特点,介绍了对燃气轮机燃烧室连结缸采用射线照相进行工艺验证采用的常规和特殊方法及照相结果分析。

The radiographic testing technique of casting is different from that of weld, and it needs higher requirements for verifying process technic with radiographic testing method. The article introduces the normal and special methods of radiographic technique used to verify the linkage cylinder quality and gives analysis for the result.
