Solving welding problems by the use of friction stir


Project timeline
July 2004
42 months
December 2007
General Information
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.
