Optimization of Swing Process Parameters for Arc AdditiveManufacturing of Multi-Directions Steel Node

基于二次回归通用旋转设计试验方法对多向钢节点电弧增材制造摆动工艺参数进行优化。建立了摆动工艺参数送丝速度、焊枪移动速度及单边摆动幅度与堆积金属宽度和高度之间的3D响应模型,并分析验证了模型的可靠性。研究了单个摆动工艺参数和摆动工艺参数交互作用对堆积金属宽度和高度的影响。利用建立的3D响应模型优化了六向钢节点电弧增材制造摆动工艺参数,采用优化的摆动工艺参数电弧增材制造六向钢节点,制造的六向钢节点平均尺寸偏差为±1.30mm,成形精度较高。

Based on the quadratic regression general rotating design experiment method,the swing process parameters of arc ad-ditive manufacturing for multi-directional steel nodes are optimized.The 3D response model between the swing process parameters wire feeding speed,welding gun moving speed,unilateral swing amplitude and the width and height of the deposited metal metal was established,and the reliability of the model was verified and analysised.The influence of the interaction between a single swing process parameter and a swing process parameter on the width and height of the deposited metal is studied.The established 3D response model was used to optimize the arc additive manufacturing swing process parameters of the six-directions steel node,and the six-directions steel node was manufactured by arc additive manufacturing with the optimized swing process parameters.The average size deviation of the manufactured six-directions steel node was±1.30mm,the forming accuracy is high.
