Project Description:
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.

Title:
Solving welding problems by the use of friction stir
Acronym: SOLVSTIR
Participants:
Helmholtz-Zentrum Geesthacht (DE), CORUS UK Ltd (UK), Onderzoekscentrum voor Aanwending van Staal N.V. (BE), Danish Stir Welding Technology (DK), Fincantieri - Cantieri Navali Italiani S.p.A. (IT), Universität Duisburg-Essen (DE)
Project Description:
SOLVSTIR will provide friction stir welded based solutions for weldability problems in steel materials and improved productivity in shipbuilding. The major six objectives of this project are related to friction stir welding (FSW) as follows: (1) to select and/or develop alternative FSW tool materials with improved performance compared to W-Re based tools, (2) to implement local pre-heat to be used in conjunction with FSW, (3) to establish a relationship between welding procedure and distortion in FSW of shipbuilding steel, (4) to develop FSW process technology allowing joining of steels with non-ferrous materials, (5) to elaborate a catalogue of metallurgical, mechanical and corrosion resistance properties of FSW welds in modern high strength and creep resistance steels, (6) to develop a dedicated computer code predicting microstructure formation across the weld zone.

Title:
Improving the competitiveness of the European steel fabrication industry using synchronised tandem wire welding technology
Acronym: SYNFAB
Participants:
CORUS UK Ltd (UK), Centro Sviluppo Materiali SPA (IT), Helmholtz-Zentrum Geesthacht (DE), Institutet för Metallforskning AB (SE), Rheinische Westfälische Hochschule Aachen (DE), Stichting Netherlands Institute for Metals Research (NL), Cranfield University (UK)
Project Description:
The overall objective of SYNFAB is to explore and quantify the benefits to the European steel fabrication industry of replacing established arc welding technologies with state of the art synchronised tandem wire technologies. The main process proposed for investigation is synchronised tandem wire arc welding (STWAW). In addition , the feasibility of using this technology for synchronised tandem arc brazing (STWAB) is to be investigated and compared. The expected deliverables include the demonstration that this technology can 1) improve productivity, 2) improve the metallurgical and mechanical properties of weldments, 3) increase control over structural distortion, and 4) reduce fabrication costs.
