Paper Abstract

Laser beam welding of primary aircraft structures manufactured from aluminum alloys is considered to have a great potential in cost saving. In order to evaluate this advantage, a technology program has been adopted at EADS, Military Aircraft. The goal was to manufacture air intake shells for the Eurofighter in a cost efficient way. Stretch formed skins and machined stiffeners are joined together with laser beam welding. The baseline for a comparison in terms of cost and weight was the conventional process based on stretch forming of thick plates and subsequent milling. The major tasks of the program have been the optimization of the twin focus laser beam welding process and the proof of the structural integrity including weld strength evaluation.
