Abstract
In this study, the effects of different welding parameters applied during laser welding of AA2024 aluminum alloy materials on the tensile strength were investigated and their optimizations were made using Taguchi and ANOVA methods to obtain the most suitable welding parameters. The variable welding parameters such as laser power, pulse duration, beam power density and pulse energy were used in the study. As a result, it was concluded that the lowest tensile strength was obtained when 1800 W laser power, 5 ms pulse duration, 6000 W/mm2 beam power density and 9.5 Joule pulse energy were used, while the highest tensile strength was obtained using 2600 W laser power, 6 ms pulse duration, 6500 W/mm2 beam power density and 9.5 Joule pulse energy. When the results of the highest tensile strength (174 MPa) and the lowest tensile strength (113 MPa) were compared, it was found that the highest tensile strength was 53.98%, which was higher than the lowest tensile strength.
