The Benefits of Plasma Steel Cutting
Plasma cutting uses GASSES to slice through steel, stainless steel, and aluminum. Essentially, the process entails directing a stream of ionized gas at high pressure and velocity through a nozzle while simultaneously heating the gas to very high temperatures using an electric arc that melts the metal. Compressed air is then used to blow away the molten metal, resulting in a smoother, cleaner cut when compared to the use of an oxygen-acetylene torch. In some cases where its important to maintain the chemical structure on either side of the cut (known as the Heat Affected Zone or HAZ), the steel is submerged underwater when it is being cut or melted.
