Aluminum Arc Welding Technology to Improve Quality and Productivity of Electric Vehicles

Abstract

In the automobile industry, the use of aluminum bodies is increasing to reduce to the weight of automobile owing to the recent carbon-neutral policy. Because of a significant competition in the electric vehicle market, the technologies for batteries and motors must be secured. In particular, the main parts of the battery are made of copper and aluminum materials, and the battery platform is also made of aluminum materials to reduce the weight. Despite the high demand for aluminum materials, aluminum arc welding is known to be a difficult process owing to pores and cracks. Therefore, this thesis aims to investigate the characteristics of welding of aluminum materials in general and arc welding technology applied to electric vehicles.
