近年来,提高焊接、切割、堆焊以及国民经济中其它高温加工业的最有效的措施之一是采用等离子技术。这种技术是基于采用在控制气氛下点着的温度达1000～30000℃的电弧放电这一原理。在工业部门,目前等离子切割技术的开发计划的特点是由机械化的气体等离子切割过渡到空气一等离子和氧气一等离子切割。与气体等离子切割装置相比,搞一台空气等离子切割装置不仅可以提高5～40毫米厚的材料的切割速度1～7倍,而且由于它有很高
In recent years, one of the most effective measures to improve welding, cutting, surfacing and other high-temperature processing industries in the national economy is to use plasma technology. This technique is based on the principle of arc discharge at a temperature of 1000 to 30000 ° C at a controlled atmosphere. In the industrial sector, the current development plan for plasma cutting technology is characterized by a plasma plasma cutting of mechanized gas to plasma-plasma and oxygen-plasma-plasma cutting. Compared with the gas plasma cutting device, making an air plasma cutting device can not only increase the cutting speed of 5-40 mm thick material 1 to 7 times, and because it is very high
