重型燃气轮机叶片无损检测 第2部分：视觉检测
Application Summary AI generated
This standard specifies the visual testing methods for detecting surface and near-surface discontinuities in heavy-duty gas turbine blades and vanes. It is applied during manufacturing, in-service inspection, and maintenance of land-based gas turbines used in power generation and industrial propulsion systems. The standard ensures consistent evaluation of casting defects, service-induced cracks, and coating degradation through direct and remote visual inspection techniques.
