Radiographic Testing of Castings
Radiographic testing of castings checks for internal shrinkage cavities, porosity, and inclusions using X-ray or gamma radiation. It ensures the structural integrity of highly stressed cast parts.
Physical-Chemical Working Principle
Radiographic testing uses X-ray or gamma radiation to detect internal flaws in castings. These rays penetrate the material and are reflected by density variations such as shrinkage cavities or porosity.
Metallurgical Relevance & Welding Risks
Misinterpreted results can lead to inaccurate conclusions, resulting in missing repairs or incorrect material choices. This can affect the safety and service life of the castings.
Shop Practice & Procedures
Use high-quality radiographic equipment with high resolution. Ensure the casting is clean and free of surface contamination. The inspection should be performed by qualified technicians who can correctly interpret the results.
