摘　　要：电弧增材制造工艺能够满足现代制造业对零件快速设计、制造的要求,但电弧增材制造件成形质量差、材料利用率低,通过优化工艺参数,可以提高成形件的材料利用率,从而提高成形质量。文章研究了焊接电流、电弧电压、焊接速度、干伸长、电弧增材制造路径、层间停留时间以及电弧增材制造方式等工艺参数对成形质量的影响,并分析了成形件的高度、壁厚等尺寸。结果表明:最优工艺参数组合包括焊接电流为120~130 A,电弧电压为18~20 V,焊接速度为5 mm/s,干伸长为15 mm,层间提升距离为2 mm,层间停留时间为60 s;其中60 s的层间停留时间有助于成形质量的提高;采用摆焊方式的成形件壁厚增加,其成形质量较好,提高了生产效率和材料利用率。Wire and Arc Additive Manufacturing(WAAM)can meet the requirements of modern manufacturing industry for rapid design and manufacturing of parts.However,the material utilization rate and forming quality of WAAM are low.By optimizing the process parameters,the material utilization rate can be effectively improved,so as to improve the forming quality.This paper studies the influences of welding current,arc voltage,welding speed,wire extension,path of WAAM,residence time of layers and mode of WAAM and other parameters on forming quality,and analyzes the height and wall thickness of parts of WAAM.The results show that the optimal process parameters are that welding current ranges 120-130 A,arc voltage ranges 18-20 V,welding speed is 5 mm/s,wire extension is 15 mm,lift distance of layers is 2 mm,residence time of layers is 60 s.Among them,residence time of layers as 60 s can improve the forming quality;the wall thickness of the parts manufactured by swing welding is increased and the forming quality is better,which is helpful to improve the production efficiency and material utilization rate.
