摘要

通过对电弧周围磁场的分析，阐明了通过外部轴向磁场控制电弧形状和性能的可行性。结合通电螺线管产生的交变轴向磁场的数学表达式，利用 COMSOL Multiphysics 和 MATLAB 软件对磁场及其分布进行了仿真，确定了磁头结构和参数对磁场及其分布的影响。根据仿真结果设计并制造了磁头，并进行了焊接工艺实验。实验结果表明，高频轴向磁场能显著压缩电弧，提高焊接穿透力。

Influence of magnetic head structure and parameters on the axial magnetic field hybrid TIG welding

Through the analysis of the magnetic field around the arc, the feasibility of controlling the arc shape and performance by the external axial magnetic field is clarified. Combined with the derived mathematical expression of the alternating axial magnetic field generated by the energized solenoid, the magnetic field and its distribution were simulated with COMSOL Multiphysics and MATLAB software, and the effects of the magnetic head structure and parameters on the magnetic field and its distribution were determined. A magnetic head was designed and manufactured according to the simulation results, and the welding process experiments were carried out. The experimental results show that the high-frequency axial magnetic field can significantly compress the arc and improve the welding penetration.
