The Austem TWB (Tailor-Welded Blank) module is a precision-engineered structural component combining sheets of different steel grades into a single blank via welding. It enables optimized material distribution—higher strength where needed, lighter gauge elsewhere—enhancing crash performance, stiffness, and weight efficiency in the vehicle’s body structure. Designed for integration into the body in white (BIW) assembly, TWB components support side panels, floor sections, and reinforcements, while reducing part count and improving manufacturability.
