چکیده مقاله :
Blades of a gas turbine are the main and most important parts of turbine machines that work in very difficult and complex conditions. Existence of discontinuities and defects in the structure of these parts cause sudden and irreparable damage. It can completely take a turbine out of operation and impose huge costs on a power plant. Therefore, pre-installation controls and inspections for these parts are of great importance. One of the safest and most reliable methods of control and inspection is the use of non-destructive tests. One of the methods that has been considered in recent years is the use of infrared waves, which in this method; Surface defects and sometimes even internal defects can be detected by using infrared cameras that operate within a certain range of the electromagnetic wave spectrum (0.8-14 nm). In this paper, we try to review the conventional methods of non-destructive testing that are used in troubleshooting blades of gas turbines, and the method of using infrared waves as an alternative method to conventional methods to be discussed.
