    General info

    Plasma cutting is a type of plasma processing of materials in which a plasma jet is used as a cutting tool instead of a cutter. In the process of plasma cutting, an electric arc is ignited between the electrode and the nozzle of the device, or the metal being cut. Gas is fed into the nozzle under pressure of several atmospheres, which is converted by an electric arc into a plasma jet with a temperature of 5000 to 30,000 degrees and a speed of 500 to 1500 m/s. The thickness of the cut metal can reach up to 150 mm. The initial ignition of the arc is carried out by a high voltage pulse or short circuit between the anode and cathode in the case of an indirect arc, and the nozzle and the metal being cut in the case of a direct arc. The nozzles are cooled by gas flow (air-cooled) or liquid-cooled. Air nozzles are generally more reliable, liquid-cooled nozzles are used in high power plants and give a better finish. The gases used to produce a plasma jet are divided into active (oxygen, air) and inactive (nitrogen, argon, hydrogen, water vapor). Active gases are mainly used for cutting ferrous metals, while inactive gases are used for cutting non-ferrous metals and alloys.

    1. Any metals are processed – ferrous, non-ferrous, refractory alloys, etc.;

    2. The cutting speed of small and medium thicknesses is several times higher than the speed of flame cutting;

    3. Small and local heating of the workpiece being cut, excluding its thermal deformation;

    4.High purity and quality of the cut surface;

    5. Process safety (no need for cylinders with compressed oxygen, combustible gas, etc.);

    6. Complex curly cutting is possible;

    7. No restrictions on the geometric shape;

    8. Can be used for non-metal products;

    9. High productivity due to high cutting speed of thin and medium thicknesses;

    10. Accurate and high-quality cuts, often not requiring additional machining;

    11. Relatively low price;

    12. In the manufacture of simple parts, plasma cutting is 2-3 times faster than laser cutting;

    1. Larger HAZ compared to laser cutting;

    2. The quality with thinner sheets and plates is worse than laser cutting;

    3. Tolerances are not as accurate as with laser cutting;

    4. Does not reach the same thickness as waterjet or flame cutting;

    5. Leaves a HAZ that is not present with a water jet;

    6. Wider kerf than laser cutting;

    7. In addition, the process itself is quite complex and requires a high qualification of the operator;

    8. The workpiece must be placed strictly perpendicular.

    9. During metal cutting, a large amount of harmful gases are released into the air.

    Plasma cutting of metal is a process of penetration and removal of the melt due to the heat received from the plasma arc. The cutting speed and quality are determined by the plasma medium. Also, the plasma-forming medium affects the depth of the gas-saturated layer and the nature of physical and chemical processes at the cut edges. When processing aluminum, copper and alloys made on their basis, the following plasma gases are used: compressed air, oxygen, nitrogen-oxygen mixture, nitrogen, argon-hydrogen mixture.

    Air

    The main constituents of air are nitrogen (78.18%) and oxygen (20.8%). The combination of these two gases is a very energy-rich mixture. Air is used as the plasma gas for cutting non-alloyed, low-alloyed, high-alloyed steels and aluminium. Normally air is used for manual cutting as well as thin sheet cutting. If unalloyed steel is cut using air as the plasma gas, the cut edges are straight and reasonably smooth. However, as a cutting gas, air increases the nitrogen content of the cutting surfaces. If such cut edges are not further machined, pores may form in the weld.

    Oxygen

    Oxygen is used as a plasma gas for cutting non-alloyed and low-alloyed steels. When oxygen mixes with the melt, its viscosity decreases, due to which the melt becomes more fluid. This usually results in burr-free cut edges and round-free top edges. It becomes possible to achieve higher cutting speeds than with nitrogen and air. Unlike nitrogen or air, when using oxygen, the cut surfaces are not saturated with nitrogen, which means that the risk of pores during subsequent welding is minimized.

    Argon

    Argon is the only inert gas that can be produced commercially using the air separation method at a volume percentage of 0.9325. Being an inert gas, it is chemically neutral. Due to its large atomic mass (39.95), argon contributes to the expulsion of molten material from the cut zone through the high pulse density of the generated plasma jet. Due to its relatively low thermal conductivity and enthalpy, argon is not a perfectly ideal gas for plasma cutting, as it only allows relatively slow cutting speeds, resulting in rounded, scaly surfaces.

    Hydrogen

    Compared to argon, hydrogen has a very low atomic mass and is characterized by a relatively high thermal conductivity. Hydrogen has an extremely high maximum thermal conductivity in the dissociation temperature range, which is due to the processes of dissociation and recombination. Initially, during the recombination and ionization of diatomic hydrogen, a large amount of energy is released from the arc. This leads to compression of the flowing arc. From the above description of the physical properties, it follows that hydrogen, by itself, is just as unsuitable as a plasma medium as argon. However, if the positive properties of hydrogen regarding thermal performance are combined with the large atomic mass of argon, then the resulting gas mixture makes it possible to quickly transfer kinetic energy, as well as a sufficient amount of thermal energy, to the material being cut.

    Nitrogen

    In terms of physical properties, nitrogen is approximately intermediate between argon and hydrogen. The thermal conductivity and enthalpy of nitrogen is higher than that of argon, but less than that of hydrogen. Nitrogen and hydrogen behave in a similar way in terms of the ability to close the arc, as well as in terms of the heat of recombination, creating a fluid melt. Thus, nitrogen can be used by itself as a plasma gas. Nitrogen, used as the plasma gas, enables fast cutting of thin-walled workpieces without the formation of oxides. The disadvantage is the relatively large number of grooves. It is almost impossible to achieve a cut with completely parallel sides. The angle of the resulting bevel depends to a large extent on the gas volume and cutting speed set in the setting. Saturation of the cut surface with nitrogen adversely affects the weldability. The increased content of nitrogen at the cut surfaces is the cause of the porosity of the welded metal.

    Frequently asked questions from KSL clients

    In order for us to make an accurate calculation of the cost of plasma cutting of metal and the timing of the service, we need to receive from you complete information about the product, a detailed specification or a drawing in one of the formats: PDF, CDR, DWG or DXF. Prices for KSL laser cutting services are determined by such basic criteria as:

    1. Volume of the order;

    2. Type of metal and its thickness;

    3. Terms of order fulfillment;

    4. Complexity of work, depending on the part to be cut;

    5. Tolling or own raw materials;

    Please note that the price of plasma metal cutting is higher than the cost of mechanical cutting, but at the same time it is comparable to the quality of the finished work. Due to the use of high-precision equipment and high speed of order fulfillment, this technology is the most profitable and practical approach to the production of metal parts today. To find out how much metal cutting costs and to order it, you can send all available drawings and drawings of products to our e-mail metalworking@ksl.ua, attach a file in the order form at the top of the page, or call us.

    The design department of KSL, depending on the complexity of the product, can absolutely free of charge develop for you a drawing of the product you are interested in, if the potential planned purchase volume is assessed by the direction manager as promising, in accordance with the requirements of the companies. To create a professional drawing by our design department, you need to provide the following information:

    1.PDF drawing or an example of a drawing / photo / drawing indicating the exact external and internal dimensions of the product you are interested in;

    2. What shape, diameter and thickness of the pipe will you use to get the finished part.

    3.Painting will or not. If so, you need to specify the RAL color and paint texture;
