Joining and Welding Research Institute - Its Mission -
The major objectives of the Joining and Welding Research Institute (JWRI), the only institute of its kind in Japan that conducts “Joint Usage/Research Center on Joining and Welding”, are to ascertain scientific truths of joining and welding processes and also contribute to development of industrial applications. JWRI has improved the efficiency, quality and performance of joining and welding, together with creation of advanced materials and composites, using various heat sources and also analysis, evaluation, simulation and other highly advanced systems for visualization.
In order to develop JWRI’s distinctive features and also meet highly-diverse demands in global society, JWRI has been reorganized in 2022. Accordingly, JWRI has consisted of three divisions: the research division of“ Materials Joining Process, for providing scientific bases for generation-conversion-transportation and interaction with materials for well-controlled multi-functional energies indispensable for the processing and constriction of advanced materials and the development of high-quality energy sources suitable for various material processing; the research division of“ Materials Joining Mechanism”, for investigation of the physical and chemical properties of high performance joints and composites produced by welding and joining, and the control of the joint microstructure by highly-controlled material processing; and the research division of“ Materials Joining Assessment”, for the construction of the total system of functional assessment for various structures from large-size welded structures to micro structures, together with the Research Center for Additive Joining Application (RAJA) for advanced processing.
