采用Ti6321A焊丝进行电弧增材制造,研究了焊枪姿态和摆动参数等工艺因素对成形的影响。结果表明,不同的焊枪角度对增材制造焊缝堆焊成形形貌具有显著的影响,当焊枪姿态由推焊变化到拉焊时,焊缝熔宽减小,余高变高,即焊缝表面铺展能力减弱;焊缝熔深在焊枪垂直时达到最大值。焊枪摆动会使增材制造表面呈现纹路特征,纹路之间的宽度直接由摆长参数决定,摆宽对焊缝熔宽有显著影响,呈近似线性关系。 The use of Ti6321A wire arc additive manufacturing, research welding gun attitude and swing parameters and other factors on the forming process. The results show that different welding torch angles have a significant effect on the shape of the surfacing of the additive-made weld. When the welding gun attitude is changed from the push welding to the pull welding, the weld width decreases and the residual height increases, that is, the weld Surface spreading ability weakened; Weld penetration reaches the maximum when the torch is vertical. The swinging of the welding torch will make the surface of the additive manufacturing surface show the characteristics of the lines. The width between the lines is directly determined by the parameters of the swing length, and the swing width has a significant influence on the weld width, showing an approximately linear relationship.
