air carbon-arc cutting

But the kerfs of the air plasma-arc cutting were wider and the cutting surfaces were easily oxidized.

两种方法切割镁合金断面都形成有重熔层,激光切割重熔层厚而致密,与母材交界处无明显的热影响区;空气等离子弧切割重熔层较薄,内部有大量气孔和残渣,切缝中、下部有明显的热影响区,最宽处达50μm。

For the problems of air plasma-arc cutting that has been existing, relativity between parameter of air plasma-are cutting has been analyzed with technical test in order to get best technical parameters and resolute way.

针对空气等离子弧切割存在的问题,通过试验对切割参数的相关性进行了分析,并给出了对不锈钢和碳素钢板进行空气等离子弧切割的最佳工艺参数,提出了工艺上的解决方法。
