Plasma Cutting Machine Working Principle Pdf
Is passed through a small chamber in which a high frequency spark arc is maintained between the tungsten electrode cathode and the copper nozzle.
Plasma cutting machine working principle pdf. The plasma arc cutting process is illustrated in fig. Adding heat to material causes the molecules in it to vibrate or move more quickly. And the cutting object material is fused to be cut. In a plasma torch known as the gun or plasmatron a volume of gas such as h2 n2 02 etc.
The so called pv duration of inclusion is 100. Principle of plasma cutting means to focus a lot of. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma typical materials cut with a plasma torch include steel stainless steel aluminum brass and copper although other conductive metals may be cut as well plasma cutting is often used in fabrication shops automotive repair and restoration industrial construction and. Normal table with collect drawer or water table.
When a solid is heated the molecules start to vibrate more vigorously. Plasma arc machining working principle diagram process details of pam. Working principle of plasma arc machining the principle of plasma arc machining is shown in the figure. The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore copper nozzle.
The temperature of the plasma is in excess of 20 000 c and the velocity. A plasma is a state of matter like a solid liquid or gas. This increases the temperature and velocity of the plasma emanating from the nozzle. Working principle of pam.
This high temperature plasma jet melts the material of the workpiece. This is a cutting system utilizing heat generated by arc discharge between the cutting object material and the electrode inside the torch. Plasma arc cutting machine with automatic torch travel was used to cut ss304 work. The plasma jet of high temperature and high speed is blown out from the nozzle.
In the plasma arc machining process the material is removed by directing a high velocity jet of high temperature 11000 c to 28 000 c ionized gas on the workpiece. More space is preferable for loading metal plate especially when you load by forklift. Section 2 introduction to plasma cutting plasma cutting basics what is a plasma. Describe the plasma arc cutting process and its applications in the pipefitting trade identify the different components of plasma arc cutting equipment and ppe required for it s use list the characteristics and hazards associated with plasma cutting safely set up the equipment adjust air pressure and current to correct.
Although it can be 40 for handhelds which means the following. Atmospheric conditions from the working zone etc. Arc discharge heat forms working gas into the plasma state of high temperature. 4 minutes of plasma cutting is working and 6 minutes is necessary for it to cool down.
