2011 Physics Procedia  
Light weight design of fuselage structures is a major goal for future aircrafts to reduce structural weight for increased efficiency regarding fuel consumption. One objective is to validate and demonstrate the technology that offer the best opportunities of weight reduction and short production time. It involves the development of laser welding technologies for difficult weldable high strength aluminum alloys, containing Cu and / or Li. Another objective is to identify and evaluate approaches
