Investigation of Mechanical Properties of Aluminum Alloys Welded by Laser Welding and Optimization of Welding Parameters Using Taguchi and ANOVA Methods

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