摘要
通过分析电弧在磁场中的受力情况,设计了磁控TIG焊接设备,对设备的工作情况进行测试,可达到预期效果。通过施加横向直流磁场,可以实现电弧的单方向偏移,解决高速TIG焊接中电弧拖后的现象;施加横向交变磁场,可以实现电弧摆动,增宽电弧的加热区域,对解决窄间隙焊接上的侧壁熔合问题有积极的影响。
By the analysis of arc force in the magnetic field, a magnetic control TIG welding equipment was designed and the working condition was tested. It can achieve the desired results. The applied transverse magnetic field can make arc deflection in a specific direction, which can solve the arc lagging of the high speed TIG welding. The applied transverse alternating magnetic field can make arc swing and broaden the arc heating area, which has the positive influence on solving the problem of fusion of the sidewall.
