近年来,等离子弧切割在国外得到了广泛应用。1961年美国就有1000多台等离子弧切割机用于生产。我国现也能制造中、小型等离子弧切割机定型产品。等离子弧切割更确切的名称,叫惰性气体(或还原性气体)高度压缩的电弧切割。它是用高压惰性气体压缩在电极和工件间的电弧而产生的电离程度甚高、气体能量高度集中、温 In recent years, plasma arc cutting has been widely used abroad. In 1961 the United States there are more than 1,000 plasma arc cutting machine for the production. China is also able to create medium and small plasma arc cutting machine stereotypes. A more exact name for plasma arc cutting is arc cutting, which is a highly compressed inert gas (or reducing gas). It is the use of high pressure inert gas to compress the arc between the electrode and the workpiece resulting in a high degree of ionization, highly concentrated gas energy, temperature
