摘要
以下引文是新闻编辑从新闻编辑提供的背景资料中获得的发明人：“材料加工设备，如等离子体A RC手电筒和激光器，广泛应用于金属材料的加热、切割、刨削和标记。例如，等离子体焊炬G基本上包括焊炬本体、诸如电极和喷嘴H的消耗品。安装在焊炬体内的中心出口孔、电气连接件和冷却和冷却通道电弧控制流体(例如等离子气体)。可选的是，采用旋流环来控制流体流动模式在电极和喷嘴之间形成的等离子体室R中。在一些等离子弧手电筒中，ret锁盖可用于保持喷嘴和/或旋流环在焊炬本体内。使用的气体火炬可以是非氧化性的(例如氩或氮)，O R氧化性的(例如氧或空气)。等离子体是手电筒被配置成产生等离子弧，该等离子弧是具有高回火度的等离子气体的收缩电离射流和高动量。
Abstract
The following quote was obtained by the news editors from the background informa tion supplied bythe inventors: “Material processing apparatus, such as plasma a rc torches and lasers, are widely used inthe heating, cutting, gouging and mark ing of metallic materials known as workpieces. For example, aplasma are torch g enerally includes a torch body, consumables, such as an electrode and a nozzle h avinga central exit orifice mounted within the torch body, electrical connectio ns, and passages for cooling andarc control fluids (e.g., plasma gas). Optional ly, a swirl ring is employed to control fluid flow patternsin the plasma chambe r formed between the electrode and the nozzle. In some plasma arc torches, a retaining cap can be used to maintain the nozzle and/or the swirl ring in the torch body. Gases used in thetorch can be non-oxidizing (e.g., argon or nitrogen), o r oxidizing (e.g., oxygen or air). A plasma are torchis configured to produce a plasma arc, which is a constricted ionized jet of a plasma gas with high temperature and high momentum.
