摘要： [PROBLEMS] To reduce the generation of fume in cutting a material to be cut typified by a steel plate with plasma.[MEANS FOR SOLVING PROBLEMS] A plasma cutting method comprising spraying a plasma arc directed through a material to be cut from a plasma torch nozzle to cut the cutting material, wherein a plasma arc formed by supplying a mixed gas as a plasma gas composed of a single gas or a plurality of gases selected from halogen gases and rare gases belonging to up to the second row elements of the periodic table and a hydrogen gas, and oxygen-, argon- or nitrogen-containing gas to a part around an electrode, and electrifying a part between the electrode and the nozzle or between the electrode and the cutting material is sprayed toward the cutting material to cut the cutting material, or wherein a single gas or a plurality of gases selected from halogen gases or rare gases belonging to up to the second row elements of the periodic table and a hydrogen gas, together with the plasma arc composed mainly of an oxygen, argon or nitrogen gas, is sprayed toward the cutting material to cut the cutting material.
摘要翻译： [问题]减少用等离子体钢板切割代替的待切割材料中的烟气的产生。解决问题的方法等离子体切割方法包括从等离子体喷枪喷射待切割材料的等离子体电弧以切割切割材料，其中通过供给作为等离子体气体的混合气体形成的等离子体电弧选自属于周期表的第二排元件的卤素气体和稀有气体的单一气体或多种气体和氢气，以及含氧，含氩或含氮气体到电极周围的部分，以及将电极和喷嘴之间或电极和切割材料之间的部分通电朝向切割材料喷射以切割切割材料，或者其中选自卤素气体或稀有气体中的单一气体或多种气体属于周期表的第二排元件和氢气以及主要由氧气，氩气或氮气组成的等离子弧被喷射到切割材料上以切割切割太棒了
