All carbon arc gouged surface areas shall be ground to clean bright metal prior to subsequent welding.
开始后续焊接前，所有碳弧气刨面区域应接地至洁净明亮的金属。
2
Connect the ground connection of the electric arc welding equipment as near as possible to the welding point on the part to be welded.
将电弧焊设备上的接地连接尽可能近地连接到将要焊接零件的焊接点上。
