Plasma process and Laser process

Plasma cutting VS Laser cutting
Laser cutting and Plasma cutting system with two types of metal cutting processes are widely used in industry. Some other process used in metal cutting as well as the use of mechanical and thermal cutting, welding, electrical power and sell electricity Jet abrasive cutting machine Compared with many of these processes, and laser cuttingsystem, plasma is considered faster and more efficient.

Plasma cutting machine process
Plasma or plasma arc cutting (PAC) process, was developed in 1950. The process was especially developed for cutting stainless steel, aluminum and copper that can not be easily cut by other processes like flame cutting. The process uses gases like argon, hydrogen, nitrogen, air and oxygen that can conduct electricity and hence have the ability to transmit energy from an electrical power source. The system involves the use of a source of electrical energy, an arc starting circuit and a plasma cutting torch. The torch is connected to the power source and the circuit through leads and cables. The electrically conductive gases transmit energy from the source of electrical power through the plasma cutting torch, which is used for cutting the material.

Laser cutting process
Laser cutting technology uses laser beams to cut materials and is used in many industrial applications like cutting, drilling, engraving, welding, ablation and structuring. The material on which the high powered laser is applied, usually burns, melts or vaporizes. In gas lasers, carbon dioxide along with other gases like helium and nitrogen, are used as a medium. On the other hand, neodymium ions and Yttrium-aluminum-garnet (YAG) crystals are used in solid-state lasers.

Plasma Cutting Process

Plasma cutting is a process that is used to cut steel and other metals of different thickness. (Or sometimes other materials) using a plasma torch. In this step, inert gas (In some units, compressed air) is blown at high speed from the nozzle; At the same time the electric arc through a gas from the nozzle to the cutting surface is thin. Gas to the plasma. Plasma heat to melt the metal being cut and moves fast enough to blow out the liquid metal cutting.

Contact the HF type high-frequency, high voltage spark to ionise the air through the head torch and start arc. This requires a flashlight to communicate with the material when starting job and is not suitable for other applications related to computer numerical control (CNC) cutting.

Pilot arc type is used for plasma for the production of the second round, avoiding the need to first contact. First, low-voltage high-current circuit is used to start a small high intensity spark within the torch body that will help create a small pocket of gas plasma This is called a pilot arc. R. flight path back to power in a head torch. R pilots to maintain itself until it is brought into proximity of the specimen as it bombs the main plasma arc cutting. Curved plasma is very hot and be in the range of 25,000 ° C (45,000 degrees Fahrenheit). [1].

Plasma is an effective way to cut the thin and thick material similar Torches phone can often be reduced to 0.5 in steel (12.7 mm) thick and strong, computer-controlled Torches can cut steel up to 3 inches. (76.2 mm) thick blades produced from plasma is very hot and very localized, "cone" to merge with them will be especially useful for cutting sheet metal in curved shapes or angles.
