Crash Response of a Repaired Vehicle-Influence of Welding UHSS Members
Noorsumar, Gulshan; Robbersmyr, Kjell Gunnar; Rogovchenko, Svitlana; Vysochinskiy, Dmitry (Peer reviewed; Journal article, 2020)Automakers generally recommend not to weld structural parts after a vehicle crash, and these should be replaced as a whole part in case of a crash event. Sectioning of these members is also not recommended and use of the ... -
