Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well.
What is Plasma Cutting?

Disadvantages of Plasma Cutting
- Larger HAZ compared to laser cutting.
- Quality with thinner sheets and plates not as good as laser cutting.
- Tolerances not as precise as laser cutting.
- Does not reach thicknesses like waterjet or flame cutting.
- Leaves a HAZ which waterjet does not.
- Wider kerf than laser cutting.
How to choose a cutting method?
Making your choice between different cutting methods comes down to the material, its thickness and application of the parts.
The recommended cutting thickness for plasma cutting is between 15…50 mm.
The recommended upper limit of material thickness for a plasma cutting service is about 50 mm for carbon and stainless steel. Aluminum should no go past 40 mm.
Everything above that is in the domain of water jet and flame cutting.
Laser cutting services should be the preferred option for sheet metal and thinner plates because of its greater cutting quality and speed. But laser cutting’s upper limit is somewhere around 25…30 mm.
Also, plasma cutting is quicker and therefore cheaper with plates starting from around 15 mm. Then again, the question comes down to the required quality. It is, though, always possible to get a nice and smooth result with post processing.
Here Are Some Of The Uses of Plasma Cutting...
Plasma cutting is used for all sorts of metal fabrication projects and is typically used in on-site construction or salvage yards. For designers and artists, the most common uses are in both signage and sculpture, as well as being used in decorative panels for interior projects.
How it works?
The plasma cutting process is a thermal cutting method. Which means that is uses heat to melt the metal instead of mechanically cutting it.
The overall mechanics of the system is always the same. Plasma cutters use compressed air or other gases, such as nitrogen. Ionization of these gases takes place to create plasma.
Typically, the compressed gases come into contact with the electrode and then ionize to create more pressure. When the pressure builds up, a stream of plasma is pushed towards the cutting head.
The cutting tip constricts the flow to create a stream of plasma. This is then subjected onto the work-piece. As plasma is electrically conductive, the work-piece is connected to the ground through the cutting table.
As the plasma arc contacts the metal, its high temperature melts it. At the same time, the high speed gases blow away the molten metal.
Advantages of Plasma Cutting
- Able to cut all conductive materials. Flame cutting, though also suitable for cutting thick metals, is limited to ferrous metals only.
- Great quality for thickness up to 50 mm.
- Maximum thickness up to 150 mm.
- Comparatively cheap for medium thickness cuts.
- Best way to cut medium thickness stainless steel and aluminum.
- CNC machines are available to provide high precision and repeatability.
- Can cut in water, resulting in smaller HAZ. Also reduces noise levels.
- Smaller cutting kerf compared to flame cutting.
- Quicker cutting speed than oxyfuel.
