Plasma and Gas Cutting Metal

If you are engaged in processing and cutting metal or just going to do this activity, this article can choose the right direction. Consider two types of metal cutting - this is the use of a traditional "gas cutter" or autogenic and plasma cutting or "plasmoreza".

Gas cutting

The gas cutter, until recently, was almost the main method of cutting metal. What is needed for this? Directly gas burner, gearbox, high pressure sleeves Cylinders with propane and oxygen. At the beginning of the work, be sure to prepare metal. Clear dirt, all kinds of contamination, rust must be sure.

The principle of operation is as follows: Using a gas cutter, first flammify the gas mixture of propane and oxygen, first for warming up the surface, adjust the adjustment is a greater flow of propane. If you carefully observe the process, then the preparedness of the metal can be understood by how it becomes wet or even wet, then the temperature you need is achieved. When the metal is completely warmed, the oxygen flow smoothly add.

Cutting can be performed based on the proportion of 10/1 - 10 parts of oxygen and 1 part of propane. The cutting speed is very affected by its quality, and you can control the sparks in the streams: the sparks in front of the cutter - the speed is low, and accordingly go behind - it means that you are very rushing. The quality of the cut seam, of course, leaves much to be desired - oxides, influx and scale will be present here.

Using a tested gas cutting time, various curly parts can be cut with a thickness of 1 to 300 mm. Nowadays, there is an additional equipment for gas cutting with the help of which the incision can be cut up to 2 meters.

In addition, this method of cutting steel does not require much costs and of course, the money cutter is quite inexpensive for money.

Plasmoreza

And now, let's talk about plasma. Seeing Plasmorez in work, if you are a fan of your business, then you will lose peace and sleep and be sure to get this equipment.

The operation of the plasma formation is based on the use of a direct current direct current arc. Metal cutting is carried out by means of plasma energy. At the time of pressing the ignition button, the current from the source and inside the apparatus and at this time will form an arc, and the compressed air passes through it, it is saturated with ions and with very high speed flies through the nozzle.

Just think - the plasma speed is twice as much as the speed of sound, not to mention the temperature that reaches such a degree that the metal is not easy melted, but evaporates. This is the power of energy! The cutting with the help of plasma has very high accuracy, and the quality of the cut can be simply admired. Scale if they are formed, then they will be very insignificant and easily removed from the cut surface.

With this equipment, you can cut various types of alloys, it is in particular aluminum, titanium, copper, cast iron, steel. For serial production, plasma cutting is simply indispensable.

However, I have no rush to rejoice, and think about the disadvantages. They have everyone, even the best.

First, this is the complexity of this equipment and of course its relevant cost, unlike the old good cutter.

Secondly, the plasmorez will not be able to cut figure and does not break the thickness of over 50 mm in steel and 120 mm (this is the highest indicator) in aluminum.

And, as one more minus, this is a taper directly the recent - on non-ferrous metals can reach 20 degrees. Although it is worth remembering that in the case of a gas cutter, it at all except steel or alloys with titanium will not resolve anything.

I would like to say that these two methods of metal processing are by no means rivals. For each of them there is appropriate application. Autogen is currently used to cut any metal structures, when dismantling, it is simply indispensable. And plasmorez, with his mad productivity, it is necessary if the work should be done very quickly, and its quality is just perfect. Mechanical engineering, cutting of metal pipes, simply cannot exist without plasma installation.
