Abstract: In recent years, the conventional material research methodologies depending on scientific intuition and trial and error have been increasingly regarded as the bottleneck for development and technological advance of manufacturing industry. Then, the innovation on material research methodology has become the international new trend of materials research and development. Materials genome technology is considered as a giant leap of materials S&T and the accelerator of new material development. The complexity and randomicity of brazing process make the design and development of brazing materials more complicated and time-consuming than ordinary materials. Materials genome initiative, as a brand new concept for advanced materials development, should also be adopted to the performance optimization and development of new brazing materials. This is of great significance to promote the rapid development of welding technology, especially intelligent welding. The three main facets of materials genome technology are high-throughput material computation, high-throughput material experimentation and material basic data. Large-scale high-throughput computation can provide abundant and systematic data. High-throughput material experimentation can quickly verify these data. Moreover, the establishment of the material database can realize (i) the effective integration of calculated data with experimental data, and (ii) their mutual complementation and mutual verification. These three elements work together and then contribute to a more close relationship between theoretical and experimental research in the process of material development. This can shorten the period of research, manufacturing and application, and reduces the development cost of new materials. In addition to the performance of material itself, developing new brazing materials also need to consider (i) physical and chemical compatibility of brazing materials and base materials, (ii) interaction (diffusion and formation of new phase) between brazing materials and base materials during brazing process. The interaction between brazing materials and base materials is very complex, as it not only depends on the brazing process (temperature, holding time, pressure, atmosphere, etc.), but is directly related to the composition of brazes and base materials. Therefore, compared with ordinary materials, the design and development of brazing materials require a more complicated methodology and a more time-consuming course. And the initiation of brazing materials genome project is of great urgency. This relies to a considerable degree on the satisfactory achievement towards three essential engineering issues, i.e. development of high-throughput computing software, high-throughput experimental methodologies and data integration system. The development of intelligent welding at present has focused mostly on fusion welding, e.g. arc welding, laser welding, etc., and has also acquired notable achievements. However, the full-intelligent control technology for brazing still lies at a fairly primitive level, and the current researches concentrate mainly on brazing equipment and brazing process control. The brazing materials play an important role in intelligent brazing. So the brazing materials genome project can facilitate the intelligentization of brazing technology. In return, the advancement of intelligent brazing will also advance the course of brazing materials genome project, as it will greatly simplify and accelerate the performance examination upon new designed brazes, and in addition, it will help to collect more real-time data for the numerous artificially created brazes. This paper discusses the three basic elements of materials genome technology and the corresponding global research status. It also analyzes the influence factors and key common problems for the adoption of materials genome technology to brazing materials development, and states dialectically the mutually reinforcing relationship between brazes genome project and intelligent brazing technology.
