Development of short distance welding concepts for airframes


Project timeline
January 2004
42 months
June 2007
General Information
The WEL-AIR framework constitutes a research and technological development project designed to generate new fundamental knowledge to develop new manufacturing approaches by using short distance joining technology for primary structural components (such as skin-frame, skin-cleat, cleat-striner etc.) of the metallic aircraft fuselage. For this purpose, optimum process-property and performance relationships need to be established by satisfying the fatigue and damage tolerance requirements. The research methodology used in this project will follow "develop - test - verify - make recommendations" steps to establish new short distance welding concepts for cost-effective manufacturing of the airframes using Laser Beam Welding and Friction Steer Welding processes. The "testing - verification" steps will be covered by conducting extensive damage tolerance analysis in terms of fatigue, fracture toughness, corrosion, as well as non-destructive testing using various joint configurations and alloy combinations.
