What is Plasma Cutting?

Workpieces made of all inductive materials are cut by highly accelerated hot plasma. which is an efficient way to cut thick sheet metal.

Whether you are creating art or producing prefabricated parts. Plasma cutters offer limitless cutting for cutting aluminum, stainless steel and more, but what is behind this relatively new technology? We’re answering the most important questions about the most important facts about Plasma Cutters and Plasma Cutting.

How plasma cutting works:

Plasma cutting is a process in which an electrically induced material is cut by highly accelerated hot plasma.

Common materials that can be cut with a Plasma Torch include steel, stainless steel, aluminum, brass, copper, and other conductive metals. Motor vehicle repair and conversion industrial construction Salvage and attrition This is because it is a high-speed and high-precision cutting at a low cost.

Plasma cutting is therefore widely used from large industrial CNC applications to small hobby companies. The use of conductive gas with temperatures up to 30,000 °C makes plasma cutting extraordinary.

Basic processes in plasma cutting and welding It is the creation of an electrical channel of highly heated ionized gas – the plasma itself – from the plasma cutter through the workpiece to be cut. A finished circuit is formed back to the plasma cutter via the ground terminal.

This is the result of compressed gas – compressed gas (oxygen, air, inert gas etc., depending on the material to be cut) which is blown to the workpiece at high speed through a focused nozzle. An arc-arc occurs between the electrode near the gas nozzle and the workpiece. This electric arc ionizes part of the gas and creates an electrically conductive plasma channel. This is because the current from the plasma cutter’s cutting torch flows through the plasma. thus providing enough heat to melt through the workpiece. At the same time, the high-speed plasma and compressed gas blow the molten metal from the heat to separate the workpiece.

The plasma cutting process is an efficient way to cut both thin and thick materials. Hand torches can cut sheet steel up to 38 mm thick, strong computer-controlled torches can cut sheet steel up to 150 mm thick due to Plasma cutting nozzles produce hot, highly localized “cones” for cutting, they are very useful for cutting and welding discs in curved or angled shapes.

Advantages and Disadvantages of Plasma Cutting
