摘要
从磁场作用下带电粒子的运动出发,运用物理学的知识分析了TIG焊接电弧中的带电粒子分别在横向磁场和纵向磁场中的运动机制及电弧形态。在横向直流磁场中,焊接电弧整体偏向一侧;在横向交变磁场中,焊接电弧呈左右摆动状态;在纵向直流磁场中,焊接电弧中带电粒子作绕轴线的高速螺旋运动,焊接电弧整体呈钟罩型。详细推导TIG焊接电弧中的带电粒子分别在横向直流磁场中的偏转幅度和在纵向直流磁场中的扩展幅度,继而推测整个焊接电弧的实际运动状态,对实际生产过程有一定参考价值。
useing of the knowledge of physics,the movement of charged particles in the magnetic field is analysed,and the movement mechanism of charged particle in the TIG welding are in the transverse magnetic fieht and longitudinal magnetic field and the arc shape are analysed.In transverse DC magnetic field,the whole welding arc bias one side;and in transverse alternating magnetic fieht, the welding arc is on the state of swinging. The charged particles in the welding arc make high-speed spiral motion around the axis in the longitudinal DC magnetic field,and the whole welding arc become bell-shaped.In this paper,the charged particle in the TIG wehting arc of its deflection amplitude in the transverse magnetic field and extended amplitude in longitudinal magnetic field are derived in detail by the author,and then the whole welding arc of actual state of motion is speculated,which has some guiding significance to the actual production process and utilization vahle.
