Plasma Arc Cutting Torch Diagram

Plasma arc cutting also referred to as plasma fusion cutting or plasma cutting is a fabrication process which employs superheated ionized gas funneled through a plasma torch to heat melt and ultimately cut electrically conductive material into.

Plasma arc cutting torch diagram.

This electrode is connected to the negative terminal of a dc power supply. The schematic arrangement of plasma arc machining is shown in fig. 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. Manual plasma welding is operated over a range 0 1 to 100a from thinner foil to 3 4 mm thickness in stainless steel nickel and nickel alloys copper.

The plasma arc torch technology was again applied in the decommissioning of the yankee rowe 167 mwe pwr in massachusetts but encountered numerous problems associated with control of the swarf from cutting. Plasma arc welding is a substitute of tig arc process offering greater welding speed and better weld quality for welding thin metal section current at 0 1a below the range of the tig arc. Further the thickness of the internals at yankee rowe was at the limits of technological experience using plasma arc torch cutting. The plasma arc cutting torch carries a tungsten electrode fitted in a small chamber.

A plasma arc cutting machine cutting the internal sections of a metal part. A plasma cutter will use this electrically conductive gas to transfer energy from a power supply to any conductive material resulting in a cleaner faster cutting process than with oxyfuel.
