Plasma cutting is an operation that cut conductive materials using a high frequency and high voltage spark to ionize a gas flow. For this purpose a pressured gas is forced through a focused nozzle at high speed toward the work piece. Then the electrical arc ionizes the gas, this conductive ionized gas is called plasma. The plasma melts the material being cut and the high velocity stream of ionized gas mechanically blows the molten metal away.
On the following diagram we can see how plasma cutting process works:
In plasma cutting there are two principal working systems, hand-held and computer numerically controlled (CNC). Hand-held is used up to 38 mm for fast and less accuracy cuts. Secondly CNC systems are used to make precise incisions up to 150 mm thick.
Gestión de Compras designs, develops and manufactures a huge range of pieces forming by plasma cutting. We work all materials and thickness that this method permit us.
There are many types of plasma cutting, it depend basically of which gas is used:
- High definition plasma cutting
- Nitrogen plasma
- Oxygen plasma cutting
- Argon plasma
MATERIALS AND PRODUCTS
To carry out this process the material cut must be conductive metals. The most common used are:
Plasma cutting is used on automotive industry to produces chassis and frames. Construction industries use that to cut and fabricate huge beams or metal-sheet goods.
Is also used in shipbuilding and mining to pipe and ventilation fabrication and repair for example.
