Radiographic Testing

During the production process of castings and welded parts, due to manufacturing process or operating experience and other reasons, hazardous defects, such as porosity, shrinkage, slag, cracks in the castings, and incomplete penetration, lack of fusion, cracks, slag in the welds, usually need to be detected by appropriate NDT methods and repaired in time. NG28 has advanced radiographic testing equipment, which can provide customers with high-quality RT services, reduce losses and save costs for customers.
