Autogenous Laser Welding of AA 2024 Aluminium Alloy: Process Issues and Bead Features

Laser welding has been proven to be promising for aerospace. Welds with high aspect ratio are produced with lower heat input compared with conventional arc-welding processes; furthermore, higher productivity and lower distortion are benefited. Nevertheless, specific issues must be addressed depending on the material to be welded. In this frame, laser welding of AA 2024 in T3 heat treatment condition, which is among the most common light metal...
