Abstract

In order to further reduce the weight, extend the life, and improve the strength and toughness of structural materials, it is essential to establish the reliability of each material including lightweight materials and actively promote the multi-materialization of materials that consist of the right materials in the right place.

In the NEDO-ISMA project, Osaka University (Joining and Welding Research Institute and Graduate School of Engineering) has conducted "Fundamental Research for Friction Joining (46)", " Fundamental Research on Multi-Material Joining Technologies (64)", and gDevelopment of Joint Performance Data-Base for Joining Technologies of Multi-Materials (64-B)" from 2013.

To utilize the new joining methods, and the data created and accumulated through these technological developments , "Joining Technology Hub" has been formed.

By using "Only one and number one" new joining methods, analysis technology, intellectual property developed at Osaka University as technical seeds, "Joining Technology Hub" will collaborate with companies and academic institution and conduct joint research and joint development aimed for practical applications .
