When the welding current is added, on the one hand, the section of arc will more or less increase, so the fusion width will increase ; on the other hand, the depth of arc crater will increase
焊接電流增加時，一方面是電
弧截面略有增加，導致熔寬增加，另一方面是電流增加促使
弧坑深度增加。
-
When the welding current is added, the quality of heat of the arc will increase, so both the volume of molten puddle and the depth of arc crater will all increase, and the weld depth will increase when the weld is cooling
焊接電流增加時，電弧的熱量增加，因此熔池體積和弧坑深度都隨電流增加，所以冷卻下來后，焊縫厚度就增加。
