When the higher powerarc is of the submerged arc type, the flux powder covering the weld metal pool must also be supported against the effects of gravity.
当高功率的弧是埋弧类型,通量粉末覆盖焊缝金属池还必须支持对重力的影响。

What some pilot plants have shown so far, however, is that a lot of the electricity produced is needed to power the arc.
然而,有些试行这项技术的工厂却发现产生电弧需要大量电力。
