Plasma cutting
Plasma cutting is basically a process that is used to cut generally steel and sometimes other metals of different thicknesses. This process consists of metal melting, and then disposing of the cut metal from the slot. This is done by means of a concentrated plasma arc, having a large kinetic energy. [11] In fact, plasma cutting uses a high
temperature that prevails in the core plasma arc and high speed plasma stream. The electric arc is formed between the tungsten electrode and the cut object. Principles of its formation is as follows: by passing the gas stream in the compressed form of the arc for the phenomenon is a result of ionization and high power density is possible to
produce a stream of plasma. The most commonly used gas plasma cutting is air and also in high-power devices used argon, nitrogen, hydrogen, carbon dioxide. [11], [13] Plasma arcs are extremely hot and are in the range of 25 000 °C. Due to the high temperature plasma cutting edge of a destructive influence on the confluence. This method we
can usually cut from 50 mm to 150 mm thick. This is a large range of metal cutting.
