Plasmalõikus

Plasmalõikus is an Estonian term referring to plasma cutting. Plasma cutting is a thermal cutting process that uses a high-velocity jet of ionized gas, or plasma, to cut electrically conductive materials. The process begins by establishing an electrical arc between an electrode and the workpiece. This arc ionizes the gas, creating a plasma stream. The intense heat of the plasma melts the material, and the high velocity of the gas jet blows the molten material away, creating a clean cut.

The gas used in plasma cutting can be air, nitrogen, argon, oxygen, or other gases, depending on the material being cut and the desired cut quality. Air is the most common and cost-effective gas for cutting carbon steel and stainless steel. Oxygen is often used for cutting carbon steel to achieve a faster cutting speed and a cleaner edge. Inert gases like argon or nitrogen are typically used for cutting non-ferrous metals such as aluminum and copper.

Plasma cutters consist of a power source, a plasma torch, and a gas supply. The power source provides the electrical energy needed to create the plasma arc. The plasma torch directs the plasma jet onto the workpiece and contains the electrode and nozzle. The gas supply delivers the chosen gas to the torch. Plasma cutting is widely used in manufacturing, fabrication, construction, and repair industries due to its speed, precision, and ability to cut a variety of metals. It can cut materials ranging in thickness from very thin sheets to several inches thick.
