Abstract
This paper describes how to make tailored blanks of front side member that were composed of high strength steel and TRIP(TRansformation Induced Plasticity) steel for weight reduction and improvement of crash load. Tailored blanks made by laser and mash-seam welding were compared with non-tailored blanks made by spot welding. Static compression tests were performed for performance comparison of each sample. Front side members made by tailored blank were superior to those made by spot welding in the initial, but those results were inverse in the last. Average load of tailored blank in six-angle type was better than that of rectangular type.
