The influence of air-arccutting on the initial stress fields contain two aspects: 1)the stresses near the groove are released because of the metal materials wiped away;
电弧气刨对于板材应力场影响包含两个方面：（1）材料的去除释放板材坡口处的初始应力；

But the argon plasma arc voltage, low enthalpy is not high, cutting ability is limited, and cut the air than the thickness of the cut about 25% lower.
但氩气等离子弧的电压较低，焓值不高，切割能力有限，与空气切割相比其切割的厚度大约会降低25%。

The arccutting technique of air plasma water re-compressed won the second prize of National Scientific and Technological Progress Award.
