Abstract:	Aluminium offers not only its low density and the good mechanical properties but also the advantage that it is extremely suitable for foaming due to the relatively low melting point. Furthermore, it offers the particular possibility of manufacturing a strong, large-area material joint, designated as an AFS (aluminium foam sandwich), due to the utilisation of a similar material combination -- conventional sheets in the cover layers and aluminium foam in the core. The semi-finished AFS products can be processed flexibly in the still unfoamed condition as well as in the already finish-foamed condition. Investigations into the welding and the resulting joint properties are necessary so that the advantages of the AFS can be used effectively as a material for welded structures. In the presented paper, systematic investigations were conducted into the weldability of AFS materials in the foamed and unfoamed conditions, mechanical-technological properties of the joints (joining nodes) were established and FEM modelling procedures were carried out.
