Abstract
Tailored blank by laser welding started in the mid-1980’s, and is currently applied to automotive body in the world. The purpose is that cost reduction and quality improvement by integrating pressed parts and weight saving by optimum layout of panel thickness and material. World production of tailored blank has been rapidly increasing by expanding applicable parts in each automaker. Toyota started to develop laser butt welding technology and tailored blank forming technology in the 1980’s. In 1989, we used tailored blank that has different material and thickness for side panel of Lexus LS before the rest of the world, and applicable parts are expanding sequentially.
