Abstract

The crash performance improvements achieved by using PressHardened Steel (PHS) based laser welded blanks are reported.The interest of using a dedicated welding process to avoidexcessive AlSi coating dilution is discussed. In-use propertiesanalysis demonstrates the interest of this concept. Case studiesare performed on door-ring and rear rails to demonstratethe strong potential in terms of weight saving and crashperformance.
