Multi materials concept design requires using different joining techniques according dissimilar materials to be joined and different geometrical configurations. There is no more a unique universal joining technique for multi materials assembling. Nevertheless dissimilar joining aluminium-steel uses same approach as steel-steel joining but using more techniques. Resistance Spot Welding is most commonly used because of low cost and process robustness, but requires accurate energy monitoring to succeed solid state diffusion welding. For joining nonweldable materials such as aluminium-steel, cold joining as self piercing riveting looks the most robust to be used when keeping the same geometrical configurations and assembly lay out. Static and dynamic requirement of light structures using lower modulus materials requires continuous joining. Addition of adhesive gluing is very efficient and enables to keep same overlap joining. New solid state such as Friction Stir Spot Welding is very promising for spot joining aluminium with equivalent spot strength as riveting is subjected to tool life duration. Semi hot welding techniques such as MIG, CMT, laser weld brazing and laser hybrid process to selected according joining speed needs to use lap edge or angle configurations but with mono side access possibilities. This enables the evolution of concept design for using more hollow sections to go to space frame architectures. Multi materials joining requires mode enlarged expertise, more interaction between concept design and processing, and moreover tighter partnership between competence suppliers and automotive end-users. Multi-materials joining is more costly than current steel-steel joining. Effort should be carried out to improve this field in order to reduce additional save weight joining over cost.
