Laser Welding of Lightweight Aerospace Alloys

This chapter provides an overview of laser welding of lightweight aerospace alloys. First, the types, functions, and principles of laser welding are discussed. Moreover, the key benefits and drawbacks of laser welding techniques compared with conventional welding techniques are thoroughly discussed. Then, lightweight alloys, aluminum and titanium alloys, in laser welding are investigated. In addition to discussing joints of similar materials, this chapter also investigates laser welding joints involving dissimilar materials. The microstructural and mechanical characteristics of laser-welded lightweight alloys used in the aerospace sector are highlighted.
