What cutting methods are most often used in industry?
We offer a course on oxy-acetylene, plasma and electric torches, which are one of the most popular tools used to separate low-carbon and low-alloy metals.
In our center you will find out all the necessary information about working as an operator. Gas cutting involves bringing the metal to temperature. It burns on contact with the burner and then volatilizes as metal oxide. Properly designed burners can mix specific proportions of combustible gas with oxygen. Materials such as propane-butane and acetylene are used as the fuel gas. Cutting with acetylene is an extremely effective method due to its high temperature properties. Its additional advantage is mobility, high quality of metal cutting and the option of mechanizing the cutting processes with their use. This method is used in many industries, incl. in small workshops or large production halls. Gas cutting can be used for machining cast iron, bronze, brass, steel and various metal alloys. In addition, for soldering, heating and burning. Gas welding consists in heating the processed material to the appropriate temperature by means of a flame, so that it degrades and changes its state of aggregation. Thanks to this, it is possible to permanently join or separate steel elements with a thickness of up to 300 mm. A properly selected type of torch is responsible for the effect and quality of the cut. The smaller burner is the smaller stream. This means more precision. Torches are used for cutting as well as for welding. However, not every metal is suitable for this method. The vulnerable metals are: bronze, brass, cast iron, iron, tungsten and titanium.
Plasma cutting is designed to melt and eject metal from the cut using a highly concentrated electric arc with a high kinetic energy value that glows between the workpiece and the non-consumable electrode. Plasma is produced by the torch. The passage of a stream of compressed gas through an electric arc causes ionization and, by high concentration of power, produces a flux. The nozzle in the torch focuses the plasma arc. The walls of the nozzle cool down and cause the column to narrow. This method uses high temperature (10,000 ÷ 30,000K) in the core of the plasma arc and the extremely high speed of the stream. This causes the material to be melted and blown out of the gap.
Air is a frequently used gas in this process. In devices with more power, mainly hydrogen, argon, carbon dioxide, nitrogen and argon-helium or argon-hydrogen mixtures are used. The plasma jet can cut through materials that are electrically conductive and are made of copper, aluminum and its alloys, brass, alloyed or carbon steels, and cast iron.

We distinguish individual advantages and disadvantages of gas cuts:
- small area of cut impact
- good surface quality
- small gap
- fast piercing
- simple process automation
- cutting thickness range - from 0.5mm to 160mm
- smooth vertical cutting
- small thermal deformations
- about 6 times faster cutting speed than oxy-gas cutting
- little influence of temperature on the element
- no overburning on thin materials
- changes in the cut impact area
- noise (not applicable for underwater cutting)
- strong UV radiation
- difficulties in maintaining the perpendicularity of the edges
- high amount of fumes and gases that are harmful to health.
