The affordable implementation of lightweight constructions in automotive engineering depends not only on the availability of suitable processing technologies for new lightweight materials but also on suitable, cost-efficient joining methods for multi-material combinations with high process reliability. Therefore, joining technology plays a key role in realizing energy-efficient vehicles. The systematic development of joining methods is necessary to overcome the metallurgical and thermal incompatibility of steel/aluminium or steel/fibre-reinforced plastic combinations. This paper presents two innovative and highly productive joining technologies and characterizes these processes based on their technological properties for one specific steel/aluminium material combination.
