摘　　要：从等离子切割的角度定义高强钢,详细阐述等离子切割工艺在高强钢上应用的适用特性。将等离子切割工艺与另外三种广泛应用的切割工艺进行对比,比较这些切割工艺对下道焊接工艺的影响。分析空气等离子切割工艺HAZ效果、切割质量和切割成本之间的关系,同时描述了高强钢等离子切割的设备要求即等离子切割电源、高度调节和CNC数控系统。The presentation gives the definition of high strength steel from the view of plasma cutting and the applicability of plasma cutting to high strength steel according to the characteristics of plasma. We compare the plasma cutting process to the 3 other widely a- vailable cutting processes as well as on the impact of the normal following welding process. The presentation mostly explain the oxygen plasma cutting process, the effect on the HAZ, cut quality and cutting cost. The specific requirements on the cutting equipment from the plasma power source to the height control and CNC requirements will also be discussed.
