A review is presented of the growth in interest in friction stir welding (FSW) as measured by real industry applications and the distribution of related patent filings by time and geography, and case studies are reported to illustrate commonly occur…

The effects of post weld heat treatments on the mechanical properties and corrosion resistance of friction stir welded dissimilar aluminium alloy joints (2024/6056) were studied. Sheets of 4 mm thickness were first joined in heat treatments T3 for 2…

Following a summary of the current applications for friction stir welding at Boeing, the Brotje Automation FSW system is introduced. Presentation slides give notes on complex contour FSW in a large work envelope, the characteristics of a robust prod…

Friction stir processing (FSP) experiments were undertaken on three Ni-based alloys (Alloy 625 (Ni, 21.6%Cr, 8.6%Mo, 3.7%Fe), Alloy 718 (Ni, 23.7%Fe, 18.1%Cr, 3.1%Mo, 1%Ti) and Hastelloy X (Ni, 21.3%Cr, 19.2%Fe, 8.3%Mo)) using a W-Re tool, process p…

The application of friction stir welding to the construction of airframe structures of precipitation-hardened aluminium alloys, using butt, lap and T-joints, is described. A landing gear strut door was manufactured by welding an Alclad 7075-T6 skin …

The friction stir welding of chromium steel (12%Cr) and of the dissimilar combination of chromium steel with low carbon steel were investigated, and the process economics compared with those of MMA, MIG and submerged arc welding. Welds were made in …

In relation to the application of friction stir welding (FSW) to the production of metallic aircraft fuselages, a report is presented into the evolution of the MUVAX (multi use vacuum assisted exoskeleton) concept within the framework of the LuFo V-…
