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.

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 Etc.

MATERIALS AND PRODUCTS

To carry out this process the material cut must be conductive metals. The most common used are:

• Steel
• Aluminum
• Brass
• Copper

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.
