摘要:: 等离子弧切割技术虽然问世不到50年，但在0.1～30mm厚的钢材切割应用中正在走向主流地位，其切割效率和切割质量在提高，切割成本在下降，不但已经用于有色金属的切割，还将发展到用于非金属切割。该文对此予以综述。
Although the plasma arc cutting technology is come to use no more than 50 years, it has becomethe main trend in cutting of steel plate with thickness from 0.lmm to 30mm. The efficiency and quali-ty of this cutting technology are advanced and its cost is descended. This technology is used in not onlynonferrous metal cutting but also nonmetal cutting in the future. The article is the summary discussionof this technology.
