Abstract

Nowadays, it is of special importance to know the precision casting parts, especially Gas Turbine parts, and to investigate the reasons for their destruction, due to their special role in power supply and oil and gas transmission. Therefore, the use of alloys capable of withstanding thermal and mechanical stresses and operating at temperatures above 800 ˚ C is essential in the manufacture of such parts. Non-destructive testing plays an important role in identifying defective components. Therefore, the use of corrective or preventive actions will be an effective step towards eradicating defects. In this study, we decided to control the behavior of parts by introducing common defects in precision casting and identifying them by X-ray Industrial Radiography. In this regard, we can mention the types of shrinkage and porosity defects as common defects, and melting temperature, feeding system, number of covering layers, regional temperature, and cooling rate of the base metal as effective factors in causing defects. Identifying and taking action to prevent or reduce defects will decrease production risk, save time, reduce initial and current costs in the application industry and increase the reliability of parts produced and efficiency.
