초록
A basic metal deposition experiment for manufacturing aluminum parts was performed using WAAM (Wire arc additive manufacturing), and the cross-sectional shape of the laminate according to nine deposition conditions. The effect of heat input was analyzed for the bead shape according to the deposition conditions, and the deposition efficiency was calculated by analyzing the cross-sectional shape of thin-wall parts made of aluminum. The amount of heat input was used in the experiment from about 2.7 kJ/cm to 4.5 kJ/cm, and the closer the heat input was to 4.5kJ/cm, the higher the deposition efficiency was. The maximum lamination efficiency obtained through this study reached 76%.
