Plasma cutting - Wikipedia ... Plasma cutting
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 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]
Plasma gasification
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 ...

Arc welding - Wikipedia ... Arc welding
Submerged arc welding. The welding head moves from right to left. The flux powder is supplied by the hopper on the left hand side, then follow three filler wire guns and finally a vacuum cleaner. Pieces of slag from submerged arc welding exhibiting glassy surface due to silica (SiO 2). Submerged arc welding (SAW) is a common arc welding process.
