  2. 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 ...

  3. Plasma cutting - Wikipedia

    en.wikipedia.org/wiki/Plasma_cutting

    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 ...

  4. Plasma torch - Wikipedia

    en.wikipedia.org/wiki/Plasma_torch

    A plasma torch cutter. 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]

  5. Electric arc furnace - Wikipedia

    en.wikipedia.org/wiki/Electric_arc_furnace

    Electric arc furnace. An electric arc furnace (the large cylinder) being tapped. Rendering of exterior and interior of an electric arc furnace. An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries ...

  7. Plasma activation - Wikipedia

    en.wikipedia.org/wiki/Plasma_activation

    Plasma activation. Plasma activation (or plasma functionalization) is a method of surface modification employing plasma processing, which improves surface adhesion properties of many materials including metals, glass, ceramics, a broad range of polymers and textiles and even natural materials such as wood and seeds.

  8. Spark plasma sintering - Wikipedia

    en.wikipedia.org/wiki/Spark_plasma_sintering

    Spark plasma sintering. Spark plasma sintering (SPS), [1] also known as field assisted sintering technique (FAST) [2] or pulsed electric current sintering (PECS), or plasma pressure compaction (P2C) [3] is a sintering technique. The main characteristic of SPS is that the pulsed or unpulsed DC or AC current directly passes through the graphite ...

  9. Plasma deep drilling technology - Wikipedia

    en.wikipedia.org/wiki/Plasma_deep_drilling...

    An electric arc is a breakdown of a gas that produces a plasma discharge, resulting from a current flowing through normally nonconductive media such as air or another gas. An arc discharge is characterized by a lower voltage than a glow discharge, and relies on thermionic emission of electrons from the electrodes supporting the arc. The ...
