Kinetic analysis of spray transfer welding arc in a longitudinal magnetic field

  • 摘要: 设计了一种工程实用性强、磁控稳定性好的纵向磁场发生装置,借助Ansys仿真软件发现电弧空间的磁场含有一定量的呈辐射状分布的径向分量。将该纵向磁场应用于喷射过渡MAG焊,利用高速摄像手段分析了电弧和液流束的运动特征。分析了电极磁场力的存在机理和特点,在此基础上通过分析不同形状电弧的受力情况,确定了电弧空间形态呈螺旋线状。

     

    Abstract: A miniaturized generator device for longitudinal magnetic field is designed.The simulation result which calculated by finite element code Ansys indicates that radial component exists in arc zone.Applied the longitudinal magnetic field to the process of spray transfer, the movement character of arc and liquid metal jet is obtained by high speed camera.On the basis of electrode magnetic force, the stress of different shaped arc can be analyzed.So the spatial shape of arc is spiral line.
