Cost Effective Integral Metallic Structure


Project timeline
September 2006
42 months

General Information
Friction stir welding (FSW) is now considered mature for simple applications and it has been shown that weight savings of up to 15% and cost savings of 20% can be achieved by its application. As a result FSW will be used in future Airbus aircraft such as A350. All major European airframe manufacturers believe that there are many more applications for FSW in the fabrication of cost effective integral metallic structure. Examples include circumferential joints, tailored blanks, window frames, stringer to skin attachment, spars, enclosed sections and fittings. Major technical advances need to be made beyond the current state of the art for FSW and integral metallic structure to achieve this. It is also necessary for FSW to be able to be applied to new geometries. Therefore the objective of the COINS project is to extend the application of integral metallic structure utilising friction stir welding by: advancing the state of the art of FSW technology; developing new geometries for FSW; and through innovations in design.
