What Is Plasma Cutting?|What Materials Can Be Cut With A Plasma Cutter?
Plasma cutting is a procedure utilized to cut steel, stainless steel and aluminium using a plasma torch. Simply put, gas is blown at a high speed from a nozzle while an electrical arc melts the metal and compresses air to blow away the molten metal.
This leaves a cleaner cut than oxygen-acetylene torch cutting.
How Plasma Cutting Works?
Plasma cutting is a process in which electrically conductive materials are cut through by methods of an accelerated jet of hot plasma. Due to the high speed and accuracy of the cuts at low expense, plasma cutting is commonly used from large commercial CNC applications to little hobby businesses where the products are consequently utilized for welding.
The standard procedure in plasma cutting and welding is to develop an electrical channel of superheated, electrically ionised gas– i.e. plasma – from the plasma cutter itself through the workpiece to be cut, therefore forming a finished circuit back to the plasma cutter through an earth terminal.
This is accomplished by a compressed gas (oxygen, air, inert gas and others depending upon the product to be cut) which is blown to the workpiece at high speed through a focused nozzle. Within the gas, an arc forms in between an electrode near the gas nozzle and the workpiece itself. This electric arc ionises part of the gas and produces an electrically conductive plasma channel.
As the present from the cutting torch of the plasma cutter streams through this plasma, it produces enough heat to melt through the workpiece. At the same time, much of the high-speed plasma and compressed gas blows the hot molten metal away, separating the workpiece.
The Advantages Of Robotic Plasma Cutting Are Numerous:
Cutting Speed
Robotic plasma cutters are 5 times faster than conventional, manual torches, and can cut up to 500 inches per minute.
Large Range of Product and Density– Plasma cutting robotics can make exact cuts in a range of densities and metals. These plasma cutters use nitrogen, which allows them to cut steel, aluminium and other metals.
Ease Of Use
Robot plasma cutters need limited training, making them user-friendly.
Multi-Tasking
Robotic plasma cutting systems are not just limited to cutting. They can be used as determinants, lining up material completely.
Security
This cutting application utilizes gas that is not highly combustible, removing a few of the security threats with gas cutting procedures.
Affordable
Plasma cutting is a cost-effective application– it is cheaper than laser or water-jet cutting.
Keeps Products Cool
Despite running at high temperatures, plasma cutting robotic systems can keep the surface of materials cool. This prevents warping and damage to paint and other finishes.
Increased Cutting Speeds
Plasma cutting, when used on metal up to 2″ thick, is capable of speeds twice as quick as cutting by oxy-fuel. The thinner the metal the much better the speed advantages.
Thinner metals enable cutting speeds that depend 12+ times faster than oxy-fuel. Cutting more parts in less time translates directly to enhanced operations and increased efficiency.
Reduced Dross
If cuts are used Oxyfuel, consolidated dross (oxide slag) is created by the chemical reactions in between the steel and oxygen. This product adheres to cuts and constantly needs sculpting or grinding to be eliminated.
In contrast, HD plasma cutting utilizes electrically charged high-temp gas which melts metal and blows the molten metal far from the cut. Because minimal dross is developed and the process itself eliminates excess metal, sculpting or grinding is usually not required.
Raised Inside Piercing Speed
Numerous cutting applications require inside the piercing. When you use oxyfuel to pierce a 1/2″ thick piece of steel, the process may take a majority of a minute because metal demands preheating to about 1830 degrees Fahrenheit (1000ºC). Alternately, high definition plasma pierces the same 1/2″ metal piece in 2 seconds, which considerably increases your store’s efficiency rates.
Removed Plate Warping
High definition plasma technology’s fast cutting speeds drastically minimize the quantity of heat that is transferred to the material. Using high definition plasma cutting avoids plate warping of thin (18 gauge to 1/4″) materials– an issue commonly affecting products that are cut more slowly by oxy-fuel.
Plasma can be safely utilized with most non-ferrous metals, many commonly sheet-pressed steel that’s under one inch thick. Plasma cutters can be discovered attached to portable kits, repaired stations, and robotic arms. Plasma is used in light and heavy markets anywhere fast, accurate, and precise cuts of flat, flexible metal are needed.
