Abstract: The flourishing development of non-destructive testing in China is witnessed by its rapid developing in almost every industrial branch for the last decade. The non-destructive testing (NDT) is the important pillar of machinery industry and is an industrial and engineering application-oriented scientific field, and hence it must be closely combined with the affairs of national economy development and must serve the large engineering projects to maintain their safety and integrity. In order to realize sustainable development of economy, the energy-saving and green manufactures have become the basic policy of national economy development. The promotion of NDT techniques in the future must be closely combined with this basic background of national economy development policy. The innovative theoretical achievements in the metal magnetic memory technique by Chinese scientists are introduced and achievements of NDT research and application in different industrial branches around China are underlined. Special attention is paid to the role played by acoustic emission based integrated NDT in the determining and prolonging the lives of two aircraft groups through full scale fatigue tests. The future development trend of NDT techniques is discussed, and finally challenges confronted by NDT workers in China and around the world are specially addressed.
