Abstract

The requirements for welding quality and structural performance are getting higher and higher with the development of modern science and technology. All kinds of advanced and special materials continue to emerge in recent years. Advanced materials have greatly promoted the progress of science and technology and social development

and have been applied in electronics

energy

vehicle manufacturing

aerospace and nuclear industry. The welding of advanced materials involves a wide range of areas because they have some characteristics of high performance

high hardness and welding difficulty. Present situation and research progress of special welding of advanced materials is clarified with the example of advanced ceramics

intermetallics and C composites

which has a certain significance for promoting the research and development of advanced materials welding.
