Laser welding of ultra high strength steels
Due to their outstanding properties, high strength steels (HSS) are ever more required by the automotive industry. Indeed, high strength steels make it possible to reduce the overall weight of the vehicles. However, manufacturing of industrial parts may be hindered by the higher hardenability of these steels. The laser weldability of different HSS joints and the beneficial effects of on-line pre- and post-heat treatments on the mechanical properties of the welds are presented.
