Lightweight composites offer high potential applications for future car body concepts. Due to the structural and metallurgical light weight constructions, sandwich materials with a core of foamable aluminium are very important for the design of modern, fuel saving vehicles. Tailored blanks with foamable aluminium sandwich material offer the possibility of near net shape design using aluminium foam sandwich only in areas, in which a increased stiffness or the increased energy adsorption ability are required. Costs and weight are saved by the optimised application of material in large surface workpieces. Complex joining elements for the connection of sandwich materials are completely omitted by the binding over the sheet metal. This will lead to a clear decrease of the process steps, which would be needed with conventional cutting and joining processes for the production of wide integral components with lightweight composite materials. Within this paper fundamentals of the process sequence laser beam cutting and welding for the fabrication of tailored blanks with foamable aluminium sandwich material are described. First results of laser beam cutting and the quality of the cutting edge are presented. The processing results and properties of laser welded aluminium sandwich material are described by metallurgical examination as well as foaming properties of the weld seam are presented.
