Application of Nondestructive Testing Technology in Manufacture,Inspection,and Repair of Freight Cars

In light of the development and features of speed increased and heavy haul freight cars in China railway as well as the circumstances and present conditions of China railway transport,generally described are the important significance of applying nondestructive testing technology in manufacture,inspection and repair of freight cars and the important role of the nondestructive testing technology in ensuring the product quality of key parts and components of freight cars and ensuring the safety in railway transport.The application range and effect of the nondestructive testing technology in manufacture,inspection and repair of freight cars are described in such aspects as importing technical standards,setting up standards and regulations,the nondestructive testing technology for key parts and components of railway freight cars,and the test equipment.And the development of nondestructive testing of railway freight cars in China is envisaged and prospected.
