    Friction Stir Welding of Aluminum Alloys

    Editor’s Note: As many articles have appeared in Light Metal Age (both in the magazine and online) describing and following the friction stir welding (FSW) process, especially its application in joining aluminum alloys in various forms and tempers, readers should be familiar with its advantages. In the FSW process, aluminum components are joined in the solid […]

    Cover Automakers are moving deeper into the development of electric vehicles. For example, for the first time ever Ford introduced a one-off Mustang Cobra Jet factory drag racer with all-electric propulsion in order to demonstrate the capabilities of electric powertrains. This is one of several models the company has developed with electric and hybrid electric […]

    Welding of Aluminum Alloys

    Experienced welders will tell you that, compared to welding steel, welding aluminum and its alloys is not difficult but different. Steel, being one of the common construction materials, most welders and myself included started by learning how to weld steel. As aluminum has especially gained market share in transportation, welding aluminum is challenged in various […]

    University of Stuttgart Develops New Friction Stir Welding Process for Joining Aluminum and Steel Plates

    The Materials Testing Institute at the University of Stuttgart has developed a process, based on friction stir welding (FSW), for the high-strength welding of aluminum and steel plates. The plates can have different thicknesses and the seam is so stable that the hybrid plates can even be deep drawn. This enables lightweight yet sturdy hybrid […]

    Nanotechnology Enables Engineers to Weld 7075 Aluminum Alloy

    Engineers at the UCLA Samueli School of Engineering developed a method for welding AA7075 alloy. Developed in the 1940s for the automotive industry, the alloy that is nearly as strong and one-third its weight, but traditionally has been almost impossible to weld together using the techniques commonly used by auto makers for the assembly of […]
