molten crater 中文意思是什麼
molten crater
解釋
焊池-
Molten lava cooled and sealed up the bottom, forming a huge bowl - shaped crater
熔巖冷卻后封住了火山底,因而形成了一個大型的碗狀火山口。 -
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。
