The DIAVEM II project aims to develop three lead-free metal glass assembly technologies: sealing, laser welding and tender brazing. In the long run, these technologies will allow, for example, the production of lighter connectors compatible with European environmental regulations. The studies will allow a better understanding of the physico-chemical phenomena involved in the different glass-metal assembly, at the time of the formation of the glass-metal bond and at the final interface. The combined know-how of the CRTs partners of this project (Cerfav, Institute of Welding and IREPA LASER) will make it possible to federate and structure a sector on the themes “glass, metallurgy, assemblages” where intimate knowledge and mastery of the implementation of materials is essential and where the actors of the Grand Est Region are already recognised. The potential impact of the DIAVEM project ranges from the electronics industry to the luxury industry, building and consumer products, and concern both miniature assembly topics and macroscopic parts assemblies. A coherent and innovative Grand Est technology offer for SMEs/SMIs and industrialists in the target sectors can be developed
