What are the characteristics of plasma cutting machine?

Plasma cutting machine is the use of plasma cutting technology for metal materials processing machinery. Plasma cutting is to use the heat of high temperature plasma to make the metal part of the workpiece incision or local melting (and evaporation), and by high-speed plasma momentum to exclude molten metal to form a cutting process.

Plasma cutting machine features:

Plasma cutting machine with different working gases can cut all kinds of oxygen cutting hard to cut metals, especially for non-ferrous metals (stainless steel, carbon steel, aluminum, copper, titanium, nickel) cutting effect is better; Its main advantage is that when cutting metal thickness is not big, plasma cutting speed is fast, especially when cutting ordinary carbon steel sheet, the speed can reach 5~6 times of oxygen cutting method, cutting surface smooth, small thermal deformation, almost no heat affected zone.

Plasma cutting machine development up to now, can be used to work gas (working gas is plasma conductive medium, but also carry heat body, but also exclude the molten metal in the incision) on the plasma cutting characteristics and cutting quality, speed have obvious influence. The commonly used plasma arc gas includes argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases.

Plasma cutting machine is widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, construction machinery, steel structure and other industries!

Plasma from water vapor is a safe, simple, effective, versatile and environmentally friendly way to heat work (cutting, fusion welding, brazing, quenching, spraying, etc.) metals larger than 0.3mm in thickness, a first in the history of the metalworking industry.

The essence of the working process of a plasma device is as follows: an arc is generated between the nozzle (anode) and the electrode (cathode) inside the gun, which ionizes the moisture between, thus achieving a plasma state. At this point the ionized vapor under internal pressure is ejected from the nozzle in the form of plasma beams, the temperature of which is about 8000° с. This allows cutting, welding, fusion welding and other forms of heat treatment of non-combustible materials.
