The experimental research vehicle ES3 body was realized by using various aluminum-joining technologies: MIG welding, laser welding, self-piercing riveting. These technologies were applied selectively to make full use of their individual characteristics, according to the body structure and joined materials. Of these technologies, self-piercing riveting is advantageous in several respects. Aiming to expand the application range of riveting technology, we developed a die that prevents cracks in joining aluminum casting, and a method to improve rivet driving in thick, multi-pile portion. We further studied the feasibility of aluminum rivets. This paper outlines the ES3 body structure and it's joining technologies used and introduces the further improvements we developed concerning self-piercing riveting.
