1、When the higher power arc 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。
2、horizontal position welding, the gravity makes molten metal flow downward and sometimes causes weld defects such as undercut and overlap.───横向焊接时由于熔化金属重力的作用,会引起熔池金属下淌,从而产生咬边以及焊瘤等焊接缺陷。
3、With higher power arcs, the weld metal pool must be supported by supporting walls or barriers against the effect of gravity and be moulded to the required surface structure.───随着高功率弧,焊缝池必须辅之以支持墙壁或屏障对重力的影响,并塑造所需表面结构。
