During bridge construction, we may use equipment such as bridge cutting machines, but do you know what the working principle of this type of bridge cutting machine is?
A processing method that uses the heat of the high-temperature plasma arc to partially or partially melt (and evaporate) the metal at the incision of the workpiece, and uses the momentum of the high-speed plasma to remove the molten metal to form the incision.
The essence of the working process of the plasma equipment is as follows: An arc is generated between the nozzle (anode) and the electrode (cathode) inside the gun, which ionizes the moisture between them, thereby achieving a plasma state. At this time, the ionized vapor is ejected from the nozzle in the form of a plasma jet under the pressure generated inside, and its temperature is about 8 000 °С. In this way, non-combustible materials are cut, welded, welded, and other forms of heat treatment are processed.
