Tailored blanks of laser-joined hybrid steel-aluminum construction
Current targets for reducing weight in automobile construction increasingly require materials to be employed in light-weight designs that can withstand loading. This results in the necessity of producing durable metallic hybrid joints. We are developing a series of joining technologies, such as laser joining, magnetic pulse welding, friction stir welding and adhesive bonding, that are matched to process steps for guaranteeing adequate joining properties. Our finite-element calculations take into account the specific coefficients of the hybrid joints when dimensioning components.
