摘　　要：为了直观地得知焊接过程中焊接电缆所产生的电磁场在空间中的分布情况,对工作中的直流弧焊机焊接电缆的工作原理进行分析,在ANSYS软件中模拟焊接工作环境,取工作时的输出电流(50A,200A),利用有限元法计算距焊接电缆不同位置的空间点的磁感应强度。在焊接过程中,输出电流的变化,对焊接电缆所产生的磁场分布产生影响,磁感应强度与电流大小成正相关;距焊接电缆的距离决定着同一输出电流时,该位置磁场强度的大小,空间场磁感应强度与距离呈负相关。利用ANSYS有限元分析方法,得到了焊接时焊接电缆所产生的空间电磁场分布特点;解决了仅依靠测量手段观测空间场的有限个点的磁感应强度,但无法得知空间场的三维分布问题。In order to intuitively know the spatial distribution of the electromagnetic field generated by the welding cable during the welding process.Analyze the working principle of the welding cable of the DC arc welding machine at work,simulate the welding working environment in ANSYS software,take the output current(50A,200A)during work,and use the finite element method to calculate the space points from different positions of the welding cable Magnetic induction.During the welding process,the change in output current has an effect on the magnetic field distribution generated by the welding cable.The magnetic induction strength is positively related to the magnitude of the current;the distance from the welding cable determines the magnitude of the magnetic field strength and the space field at the same output current.There is a negative correlation between magnetic induction and distance.The ANSYS finite element analysis method was used to obtain the magnetic field distribution characteristics of the space electromagnetic field generated by the welding cable during welding.It solved the problem of observing the three-dimensional distribution of the space field only by measuring the magnetic induction intensity of the finite points of the space field by means of measurement.
