It is suggested that high resistance grounded method and automation arcblow-out coil parallel resistance grounded method should be used for power distribution system.
建议选择高阻接地方式及自动调谐消弧线圈并联电阻接地方式。

The surface tension, arcblow force and electromagnetic force work positive to improve the penetration, and the buoyancy can increase the width in the middle of weld pool.
表面张力、电弧吹力和电磁搅拌力均有利于获得较大的熔深，浮力有利于增加焊缝中间部位的宽度。
