Laser Welding of Aluminum Alloys

This book chapter investigates the use of laser welding as a viable method for joining aluminum alloys. Aluminum alloys are widely used in various industries due to their desirable properties, including being lightweight and having high strength and corrosion resistance. Welding is an essential joining process for aluminum alloys, but it poses several challenges, such as porosity, cracking, and distortion. Laser welding has emerged as a promising technique for welding aluminum alloys due to its high precision, minimal heat input, and fast processing speed. The study focuses on the effect of process parameters such as laser power, welding speed, and focal position on the weld quality and mechanical properties of the joints. The microstructures and mechanical properties of the dissimilar and similar welded joints are also studied. Further research is needed to explore the potential of laser welding for joining other materials and to optimize the process parameters for specific applications. Overall, this book chapter contributes to advancing the knowledge and understanding of laser welding of aluminum alloys, as well as its practical implications for the industry.
