Microstructure evolution and porosity suppression in high-power laser-arc hybrid welded thick aluminum alloy T-joints through high-frequency beam oscillation

Journal of Materials Research and Technology
The mechanical properties of aluminum alloy T-joints are critically influenced by the microstructural characteristics and porosity distribution. This study systematically investigated the effects of the laser oscillation frequency from 100 to 300 Hz on ...
