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 […]

Lightweighting has been and continues to be a major concern for the aerospace, automotive, and transportation industries. Whether it’s an airplane, automobile, boat, or train, the use of lightweight materials, such as aluminum, provide significant fuel savings and performance benefits. Like its competitors in the lightweighting arena (steel, composites, etc.), aluminum is working to continually […]

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 […]

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 […]
