Roadmap on Joining Technologies for Aluminum Structures

Tadashi Aiura

Abstract:

'Aluminum Joining Technology Road Map 2018 Edition' indicates directions of technical developments of Aluminum Joining for next 30 years. The analysis was carried taken into account not only application technologies even academic basic research tasks. One of the important future market requirements is to support the growth of multi-material-body structure trends of cars. low heat-input joining methods such as solid-state welding, a mechanical joining and adhesive bonding prepared for dissimilar material joining are potential solutions with firm reliability. In terms of the process technologies, significant expansion of applications of robotics employing AI and IoT in the future joining production sites was predicted. Furthermore, the three-dimensional additive manufacturing, remote laser welding, FSW with injection of fillers and a fluxs free brazing are developed to be commonly in use. Moreover, effective solution technologies on safety issues were also required.
On the other hand, the future aspects regarding the aluminum resource issue such as material recycling were also investigated. To be more specific, an establishment of separation technologies of joined parts, in order to assist to build a social system of aluminum structures.
In an attempt to accurate prediction, of future technology trends and subjects, eight potential joining methods were deeply investigated in the 2018 edition. Potential technologies under researching were included as well as conventional joining methods like fusion welding. In particular, dissimilar material joining technologies were analyzed from mechanical and metallurgical points of view. Summarized combinations are iron, titanium, magnesium, Copper, ceramics and plastics with aluminum in the various structures.

Biography:

Dr. Tadashi Aiura, executive director of Japan Light metal Welding Association, obtained a diploma in metallurgy from the Engineering Faculty of Kyushu University. He pursued graduate’s study to obtain a master’s degree in 1984 and doctor’s degree in 1999. In 1984, he started to work with Kobe Steel, where he researched Aluminum alloys for extrusions and their fabrication technologies at Research Laboratory. He has developed various of alloys for miller finish products such as photo-receptors and polygon-miller for laser device. From year 2000, he started to work on development of aluminum alloys and aluminum parts for automotive use. Since 2010, he had roles at committees of Aluminum Association and Japan institute of light metals. From year of 2017, he has work with Japan Light Metal Association to date. He was awarded a distinguish service award by above organizations. He is one of the organizing committee members. To attract Inalco to Japan, he made an effort as the member of organizing committee of INALCO2019.
