Abstract

By means of a transverse flow 5 kW CO2 laser with low-order mode laser beam output, 1-4 mm thick aluminum alloy plates 6063 and LY12 were successfully butt welded. The result shows that the butt weldability and the weld quality of the aluminum alloy plates are mainly dependent on incident laser power density, laser beam defocused distance and shielding gas. The relationship between the weld quality of the aluminum alloy plates and the welding parameters is discussed. The macrostructure and microstructure of welded seams are analyzed. The mechanical properties of the welded seams are discussed.
