  Pipe cutting machine Are there thermal effects?Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases. At present, plasma cutting machines are widely used in various industries such as automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, engineering machinery, steel structures and other industries. Plasma cutting has developed to the present. The conductive medium of the arc is also a heat-carrying body, and at the same time, the molten metal in the cut must be excluded), which has a significant impact on the cutting characteristics of the plasma arc, as well as the cutting quality and speed.
  Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to locally melt (and evaporate) the metal at the cut of the workpiece, and uses the momentum of high-speed plasma to remove the molten metal to form the cut. Plasma cutting with different working gases can cut a variety of oxygen cutting difficult-to-cut metals, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel); its main advantage is that cutting of metal with small thickness At that time, the plasma cutting speed is fast, especially when cutting ordinary carbon steel sheets, the speed can reach 5-6 times that of the oxygen cutting method, the cutting surface is smooth, the thermal deformation is small, and there is almost no heat affected zone!
