How do you get the required licences?
We organise courses on acetylene-oxygen, plasma and electric torches, which are some of the most popular tools used to separate low-carbon and low-alloy metals. W our centre you will learn all the information you need to know about working as an operator. Gas cutting involves bringing metal up to temperature. On contact with the torch, it is burned and then escapes as metal oxide. Appropriately designed torches can mix specific proportions of combustible gas with oxygen. Materials such as propane-butane and acetylene are used as combustible gas. Cutting with acetylene is an extremely efficient method due to its ability to reach high temperatures. Its additional advantages are mobility, the high quality of metal cutting and the option to mechanise cutting processes using it. This method is used in many industries, including small workshops or large production halls. Gas cutting can be used to process cast iron, bronze, brass, steel and various metal alloys. In addition, for brazing, heating or tanning. Gas welding involves heating the workpiece material by means of a flame to a suitable temperature so that it degrades and changes its state of aggregation. This makes it possible to permanently weld or separate steel workpieces as thick as 300 mm. The correct type of torch is responsible for the effect and quality of the cut. A smaller torch means a smaller stream. This means greater precision. Torches are used for cutting and also for welding. However, not every metal is suitable for processing with this method. Suitable metals include bronze, brass, cast iron, iron, tungsten and titanium.
Plasma cutting, on the other hand, aims to melt and eject metal from the cutting gap by means of a highly concentrated electric arc with high kinetic energy, which glows between the workpiece being cut and the non-fusible electrode. The plasma is generated by a torch. Passing a stream of compressed gas through the arc causes ionisation and, through high power density, produces a jet. The nozzle, which is located in the torch, focuses the plasma arc. The walls of the nozzle are cooled and cause the column to constrict. This method uses a high temperature (10000÷30000K) at the core of the plasma arc and an extremely high jet speed. This causes the material to be melted and blown out of the slit.
In this method, the gas often used is air. Higher-powered units primarily use hydrogen, argon, carbon dioxide, nitrogen and argon-helium or argon-hydrogen mixtures. The plasma jet can cut materials that conduct electricity and are made of copper, aluminium and its alloys, brass, alloy or carbon steels and cast iron.
Advantages that distinguish plasma cutting:
- small impact area of the cut
- good surface quality
- small gap
- rapid penetration
- simple process automation
- cutting thickness range - from 0.5mm to 160mm
- efficient vertical cutting
- low thermal deformation
- Approximately 6 times faster cutting speed than oxygas cuts
- low temperature effect on the component
- no burning of thin materials
Disadvantages that distinguish plasma cutting:
- changes in the impact area of the cut
- noise (not applicable in underwater cutting)
- strong UV radiation
- difficulties in keeping edges perpendicular
- high levels of fumes and gases that are harmful to health.
