Effect of Plasma Fuse Additive Manufacturing Process Parameters on the Formability of RT-1400 Titanium Alloy
The influence of different plasma fuse additive manufacturing process parameters on the formability of RT-1400 titanium alloy was studied by quadratic regression orthogonal experiment.The results show that the welding speed has the greatest influence on the welding width,and the interaction between power and welding speed has the least influence on the welding width.The effect of wire feeding speed on the melting height is the greatest,and the effect of welding speed on the melting height is the least.The interaction between power and wire feeding rate has the greatest influence on aspect ratio,and the welding speed has the least influence on aspect ratio.The melting depth is mainly affected by the heat input,i.e.the power.The error between the predicted value and the actual value of the quadratic regression model is less than 10％.The suitable parameters for the plasma fuse additive manufacturing process of RT-1400 titanium alloy:welding power P=3 kW,wire feed speed WFS=2.4 m/min,scanning speed Ts=0.2 m/min,welding pass spacing=5.3 mm,using interlayer orthogonal scanning mode.
