First we are starting the comparison of Oxyfuel Cutting. With this technique of metal cutting, a torch is being used to heat the metal to great temperature. The strong flow of oxygen that is poured over the metal counters with the metal surface in which we are working on with a chemical reaction- oxidizes the steel on which we are working and puffing it away to structure the cut that we are aiming for. In fact an interesting thing here is the heat formed during this process is a byproduct of the method. Oxyfuel is a metal cutting process that is for the most part used for cutting out mild steel which would be of 3/8 in. to 12 in. in thickness. This is a technology that is not well thought-out to be impractical for metals such as aluminum or stainless steel, save for that they can be used for metal like that of titanium. This is a technique that has an extremely huge heat-affected region when it is put side by side and compared with the other metal cutting technologies that is in practice.
Next we are gonna see about the Plasma Cutting, one of the widely used techniques for best cutting results. What happens when gas is heated to a very high temperature is it gets ionized. At this particular moment this electrically conductive ionized gas that results turns out to be an extremely high energized substance called plasma. In plasma cutting process a high-velocity powerful stream of plasma is showed on to the metal piece that is to be worked on, at this point an electrical arc is carried along with it. The energy that actually melts and blows out the metal is the heat of the arc as well as the stream of ionized gas that blows away the molten metal away. For the purpose of this analogy, a high-density plasma system which is also known to be a high-definition systems is been used. Plasma cutting is a technology that gives way to a best resultant cut on the metal for the reason that the most recent type of nozzle technology noticeably tightens the arc to give out even more energy density.
The next metal cutting technique that is equally popular and widely used is the Laser Cutting. This is comparatively one the most modern techniques available in the market. A laser emitter emits a very low-divergence ray of light energy along with a sharp and distinct wavelength which is when later focused on to a particular spot, is proficient of cutting that metal piece. In the beginning laser cutters were limited for thing metal sheets by as time went on it came into being that these laser cutters were used to cut thicker metal sheets and rods. Laser cutting machines area widely liked and chosen among fabricating shops for the reason that they can smoothly move over from one metal sheet to another quite quickly and can take care of any variable thickness.
