  • Plasma arc welding - Wikipedia

    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 ...

  • Plasma cutting - Function, advantages and disadvantages

    Jun 25, 2019 · The basic process in plasma cutting and welding is to create an electrical channel of superheated, electrically ionised gas – i.e. plasma - from the plasma cutter itself through the workpiece to be cut, thus forming a finished circuit back to the plasma cutter via an earth terminal. This is achieved by a compressed gas (oxygen, air, inert gas and others depending on the material to be cut) which is blown to the workpiece at high speed through a focused nozzle.

  • Plasma cutting - Wikipedia

    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 repair and restoration, industrial construction, and salvage and scrapping operations. Due to the high speed and precision cuts combined with low cost, plasm

  • How Plasma Cutters Work | HowStuffWorks
