  • Plasma cutting - Wikipedia

    Apr 13, 2017 · Plasma arc welding is a liquid state welding process in which, the metal to metal joint forms in molten state. The hot ionized gases are known as Plasma. These hot ionized gases used to heating the work plates, and the joint is created due to fusion.

  • What do you need to know about plasma arc machining?

    The plasma arc formation begins when a gas such as oxygen, nitrogen, argon, or even shop air is forced through a small nozzle orifice inside the torch. An electric arc generated from the external power supply is then introduced to this high pressured gas flow, resulting in what is commonly referred to as a “plasma jet”.

    success. Plasma arc machining (PAM) is one of the widely used unconventional machining method that is capable of producing the complex shapes. There are certain process parameters such as gas pressure, cutting speed, arc voltage, arc current, standoff distance and gas flow rate that affect the quality distinctiveness of plasma cut like bevel angle, heat affected zone (HAZ), kerf generated and surface finish. Due to its improved weld quality and increased weld output it is been used for precision welding of surgical instruments, to automatic repair of jet engine blades to the manual welding for repair of components in the tool, die and mould industry. PAM and its assisted processes as well as optimization techniques, which made some new research scopes in the PAM. But due to its high equipment expense and high production of ozone, its been outnumbered by other advance welding equipments like laser beam welding …
