Arc Burns. Localized points of surface melting caused by arcing between electrodes or ground and pipe surface.
电弧烧伤。由于电极(含接地极)与管子表面之间起弧而产生的局部表面熔化点。
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。
In the end, arc, processing and ground is large diameter conical parts, along the X axis into to, is the same, but the linear cutting speed is constantly changing, the cutting surface quality changes.
在加工端面、圆弧、圆锥以及蹊径直径相差较大的零件时,沿X轴方向进给时,固然进给速度不变,但切削线速度却不断地变化,导致加工表面质量变化。
