Mankind has been processing metals for many centuries. Stamping, forging, and, of course, cutting allow you to get the desired part from the workpiece. At the same time, the level of development modern technologies allows you to move further and further away from simple, mechanical cutting of metal (especially of large thickness). Laser, waterjet and plasma cutting are increasingly used in industry (and not only). Our steel pipe cutter is also a step forward compared to a manual cutter. Let's talk about the plasma method of metal processing in more detail.

A bit of theory

Since the school course of physics, everyone knows that any substance has three states - solid, liquid and gaseous. They brought a piece of ice from the street - it melted and turned into water, and if you heat it on the stove, it will turn into steam - everything is easy and simple. However, there is a fourth state of matter - plasma. In relation to metal cutting technology, the word "plasma" means a working fluid (gas), which, under the influence of high temperatures, is ionized and becomes a conductor. Yes, this is not a "classical" stellar plasma, which is essentially a crumb of elementary particles. But the high temperature (the count goes to thousands and tens of thousands of degrees) makes it possible to use such a plasma for cutting metal. Let's look at the implementation of this method directly "in the hardware."

Physical implementation

A pipe cutter for steel pipes working with the help of plasma cutting of metal is, in principle, simple. Initially, an electric arc is ignited between the material being cut and the electrode of the apparatus. An alternative solution is to create an arc in the apparatus, between the electrode and the nozzle itself. Ultimately, we need a result - an electric arc, and we got it. Then the working medium, most often gas, begins to flow into this arc under high pressure. Under the influence of the high temperature of the latter, it turns into a plasma, the flow of which cuts the material.

As a gas, you can use both ordinary air and other substances - for example, nitrogen, argon, hydrogen, and even water vapor. The applicability of one or another working fluid depends on the type of material being processed. For cutting ferrous metals, active gases are used (air or pure oxygen), for cutting non-ferrous metals, inactive gases are used (all the same nitrogen, argon and hydrogen).

In terms of design, a classical plasma system consists of several main components. The first is the power supply. It can work both from a conventional network with a voltage of 220V, and from an industrial three-phase one. It undergoes a transformation alternating current in a constant, also the power source allows you to adjust the current strength required for operation - depending on the type of metal being processed and its thickness. Traditional systems plasma cutting allows you to get a current strength of the order of 12-20 thousand amperes per square inch (most equipment of this type is foreign, so the metric systems are appropriate).

The steel pipe cutter features better precision and surface finish. The value of the current during its operation can also reach quite large values. The second most important component of the system is the arc ignition device. A small alternating current circuit with a voltage of about 5 kV forms a spark that ignites the working fluid of the system, its other name is the pilot arc. The third component is the plasmatron itself. Its purpose is leveling and cooling (in some cases - liquid) Supplies. These include the electrode, nozzle and swirler of the working fluid. The last important part is the compressor, which pumps gas into the apparatus.

Industrial plasma cutting systems are usually equipped with drives that allow you to more accurately position the flow of the working fluid relative to the surface being processed. There are both manual and CNC systems.

Advantages and disadvantages of plasma cutting

Plasma cutting has a number of advantages over other metal cutting methods. First of all - high processing speed, especially when working with sheets of small and medium thickness. In this case, the maximum thickness of the sheet can reach 200 mm. The second advantage is the ability to work with any metals, because the temperature of the working fluid is measured in tens of thousands of degrees. The third advantage is practically complete absence thermal deformation of the processed material. And, of course, we recall that a pipe cutter for steel pipes provides excellent cut quality and the ability to obtain parts of any shape. In addition, plasma cutting is a safe process - because it does not use pressurized cylinders or combustible gases.

There are also disadvantages - the design of the system is quite complicated, which affects both the cost of one cutting operation and regular Maintenance. The flow of the working fluid flies out at a speed close to the sound - the corresponding noise level. Also, when using nitrogen as a working fluid, care should be taken to remove harmful substances that form during the operation of the system. However, the above disadvantages are not critical, so that equipment for plasma cutting of metal is becoming more widespread.

The method of cutting round and shaped pipes with plasma is one of the most productive and efficient. This technology actively used for cutting pipes of various diameters and sections, angles, sheet metal, channel, profile. Plasma cutting of metal provides a high speed of the process, the thickness of the cut material can be up to several centimeters. This technology was invented before the Second World War, but its mass use in industry with the release of the necessary machine tools was established only in the middle of the last century.

Our company provides services for cutting round and profile pipe plasma cutting method. The modern equipment used for the operation allows making holes, removing saddles, cutting in length for products with a diameter of up to 30 cm.

How does plasma cutting of metal structures work?

The main cutting tool various materials such a method is a plasma jet, preheated to 20-40 thousand degrees. The technology allows processing steel of a large number of grades, including alloy compositions, while the processing speed is 25 mm per second. It is allowed to use plasma cutting for non-ferrous alloys and aluminum blanks.
The procedure for cutting a pipe on a plasma machine consists of a series of sequential operations:

The pipe to be processed is laid on a turntable, while it is provided with freedom of rotation along the longitudinal axis.
The second end of the workpiece is clamped by rotary machines.
The turntable and cutter start working.
Cutting the workpiece is possible in both planes (horizontal and vertical) due to the possibility of its rotation and horizontal movement.
As soon as the job is done, the machine turns off.
The pipe section is removed with a special tool.

The highest level of automation and technical equipment production allows you to use only equipment (machine) and the work of a qualified specialist to perform the operation.

Advantages of plasma cutting of rolled metal

Among the existing options for cutting steel pipes, plasma cutting is among the safest, highest quality, cost-effective, and accurate. To perform the operation, only the participation of the operator and the use of appropriate equipment is required.

What gas is used for plasma cutting?

Plasma cutting can be used different types gases. Their choice is based on ultimate goal and type of material being processed.

The use of air as a plasma gas is an economical method. With the help of air, almost all metals are cut: black steel, copper, stainless steel, brass. The quality of the processed workpiece is average.

If necessary, achieve best quality use oxygen. With it, the amount of slag on the underside of the workpiece is minimal.

Cutting with the use of protective gases is typical for advanced and expensive equipment. For cutting on such machines, nitrogen, oxygen, argon and air are used. Thanks to protective gases, plasma cutting of thick workpieces (up to 5 cm) is close to laser in quality.

Types of plasma cutting machines

The modern equipment used by our company to perform the operation is equipped with electronic control. Thanks to CNC machines, plasma cutting is performed with high precision with little or no human intervention.

Unlike classic oxy-fuel pipe cutting equipment plasma installation allows you to process a metal surface with extreme precision. Due to their functionality, such machines are able to perform auxiliary operations in the form of preliminary surface preparation, edge cutting, chamfering and seam cleaning. Existence of exact drives provides a possibility of movement of installation on a pipe.
