Plasma arc cutting is a method used to cut using electrical arcs. The process was developed in the 1950s and is often referred to as plasma arc welding, which is used in the welding process. The process is widely used in the fabrication of metals and other materials and is also known by several other names such as gas tungsten arc cutting (GTAW) or plasma cutting.
Plasma arc cutting works by passing a jet of hot plasma through a narrow gap between a torch holder and the material being cut. An arc is created when an electric current is conducted through the plasma jet, it generates a tremendous amount of heat, which is then focused on the material being cut. With the heat being focused in the desired area, the metal melts and evaporates, resulting in a cut.
This method of cutting offers several advantages compared to other methods of cutting. It is a cost effective method of cutting as the process requires a small amount of electricity compared to other types of metal cutting. It also offers high levels of accuracy, as the narrow gap between the torch and the material allows for precise cutting. In addition, plasma arc cutting can be used in a wide variety of materials and with a wide range of thicknesses, from thin sheet metal to thick steel. The process is also fast and produces minimal waste, which makes it one of the most efficient methods of cutting metal.
Another advantage of plasma arc cutting is its safety. There are no dangerous chemicals involved, instead it is an electrical process. This makes it much safer to use than other types of cutting, such as oxy-fuel cutting, which produces combustible gases. The methods also produce less noise than other types of metal cutting, making it ideal for jobs in busy and noise-sensitive areas.
Overall, plasma arc cutting is a great option for jobs requiring precision and accuracy. The process is cost effective, fast and produces very minimal waste. It is also much safer than other types of cutting, with no dangerous chemicals involved. It is an ideal method for cutting a wide range of materials, including metals, plate steel, and even plastics. With its many advantages, it is no wonder why plasma arc cutting has become such an integral part of the manufacturing industry.
