3. Plasma cutting - Wikipedia

   en.wikipedia.org/wiki/Plasma_cutting

   Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops, automotive ...

4. Plasma etching - Wikipedia

   en.wikipedia.org/wiki/Plasma_etching

   A plasma etcher, or etching tool, is a tool used in the production of semiconductor devices. A plasma etcher produces a plasma from a process gas, typically oxygen or a fluorine -bearing gas, using a high frequency electric field, typically 13.56 MHz. A silicon wafer is placed in the plasma etcher, and the air is evacuated from the process ...

5. Plasma torch - Wikipedia

   en.wikipedia.org/wiki/Plasma_torch

   A plasma torch (also known as a plasma arc, plasma gun, plasma cutter, or plasmatron) is a device for generating a directed flow of plasma. [1] [2] [3] The plasma jet can be used for applications including plasma cutting, plasma arc welding, plasma spraying, and plasma gasification for waste disposal. [4]

6. Laser cutting - Wikipedia

   en.wikipedia.org/wiki/Laser_cutting

   The maximum cutting rate (production rate) is limited by a number of factors including laser power, material thickness, process type (reactive or inert), and material properties. Common industrial systems (≥1 kW) will cut carbon steel metal from 0.51 – 13 mm in thickness. For many purposes, a laser can be up to thirty times faster than ...

7. Plasma arc welding - Wikipedia

   en.wikipedia.org/wiki/Plasma_arc_welding

   Plasma arc welding ( PAW) is an arc welding process similar to gas tungsten arc welding (GTAW). The electric arc is formed between an electrode (which is usually but not always made of sintered tungsten) and the workpiece. The key difference from GTAW is that in PAW, the electrode is positioned within the body of the torch, so the plasma arc is ...

8. Atmospheric-pressure plasma - Wikipedia

   en.wikipedia.org/wiki/Atmospheric-pressure_plasma

   Atmospheric-pressure plasma. An atmospheric-pressure plasma jet formed by helium flowing through a concentric dielectric barrier discharge (DBD) Atmospheric-pressure plasma (or AP plasma or normal pressure plasma) is a plasma in which the pressure approximately matches that of the surrounding atmosphere – the so-called normal pressure.
