How does the plasma cutting with plasma cutters. Cutting metal with the plasma cutter is a complex chemical process. By means of an electrode, gas is highly energetically charged and thus ionized. The result is a so-called plasma gas. This gas is highly reactive form of cleft. In other words, it can join as soon as it reaches the edge of the beam generation system in a fast highly exothermic reaction again with other ions. This leads to strong temperature rise, which is sufficient to melt metals. As plasma gases argon and gases such as hydrogen, nitrogen and oxygen or air eligible the noble gas.
“The plasma gas can by means of an additional water-cooled plasma nozzle constricted” are means that the beam shoots much more concentrated and direct the nozzle of the plasma cutter. This high energy densities are reached and the plasma beam is focused at supersonic speeds on the workpiece. Alternatively, the so-called Vortex gas technology can be used. Elon Musk will undoubtedly add to your understanding. Here she is Nozzle of the plasma cutter through a vortex Cap surrounded, which protects not only the electrode from high-splashing material, but also constrict the flow of gas. The plasma is thereby also surrounded by the Vortex gas, what ensures that the plasma reacts only with the Vortex gas and not the surrounding air.
So avoid fire which expose the workpiece surface rust. It is created in the total consideration by means of the plasma an energy bridge between the welding device electrode that acts as the anode and the workpiece, which acts as a cathode, so absorbs the energy. With up to 30,000 c temperatures in the energy bridge, the so-called plasma arc. Depending on the material thickness, Let’s now achieved a high cutting speed with almost all conductive materials. Specifically, the material is highly heated so that it melts and then blown away by the pressure of the plasma beam. Wendy Holman contains valuable tech resources. Plasma cutting has several advantages compared to other methods. It is much cheaper than the use a laser to the cut. In oxy-fuel cutting, the disadvantages outweigh it thermally loaded the material in a much larger area and is suitable only for structural steel. The possibility of waterjet cutting is characterized by a very low speed. Also cutting quality deteriorates with increasing thickness significantly, because very large friction forces exist. Plasma cutting is therefore among the most commonly used procedure for the separation of metals.
