Plasma cutting is a metal fabrication process that uses a high-velocity jet of ionized gas (plasma) to cut through electrically conductive materials. Here's a simple explanation:
Plasma Torch:
A plasma cutting system consists of a plasma torch, which includes a nozzle and an electrode.
Gas Supply:
Inert gases, such as nitrogen or argon, are fed into the torch. When activated, these gases become ionized and form plasma.
Electric Arc:
An electric arc is created by passing an electrical current through the ionized gas, turning it into a high-temperature plasma jet.
Cutting Material:
The intense heat of the plasma jet melts and blows away the material being cut.
Precision Control:
The plasma torch can be precisely controlled to follow specific cutting paths, allowing for intricate shapes and designs.
Types of Plasma Cutting:
Manual Plasma Cutting: Hand-held plasma torch operated by a person.
CNC Plasma Cutting: Computer-controlled system for automated and precise cutting.
Materials Cut:
Plasma cutting is suitable for various metals, including steel, aluminum, copper, and stainless steel.
Applications:
Widely used in metal fabrication, construction, automotive, and other industries for cutting metal sheets and plates.
In simple terms, plasma cutting is a process where an electrically conductive material is cut using a high-temperature plasma jet produced by ionizing inert gases through an electric arc.
