Abstract
High Mn steel has been developed for automotive applications since the steel has an excellent combination of strength and ductility. However, high Mn steel has a few problems related to its chemical compositions in welding. In this study, development of dissimilar laser welding technology has been investigated for expanding application of high Mn steel. The results have shown that dissimilar weld joint between high Mn steel and carbon steel has poor mechanical properties using STS309L filler wire or not.
