Plasma Cutting Machine Working Principle Pdf

The plasma arc cutting process is illustrated in fig.

Plasma cutting machine working principle pdf.

Machine plasma cutting machines use water for cooling so the whole shift can work without interruption. Working area flat cutting table cutting no collector table stepper motor providing 1 meter of space on each side of the cutting area is enough to operate the cnc plasma cutting machine. Normal table with collect drawer or water table. Plasma arc machining working principle diagram process details of pam.

Working principle of pam. Although it can be 40 for handhelds which means the following. 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. Atmospheric conditions from the working zone etc.

The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore copper nozzle. The so called pv duration of inclusion is 100. 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. Plasma arc cutting machine with automatic torch travel was used to cut ss304 work.

This is a cutting system utilizing heat generated by arc discharge between the cutting object material and the electrode inside the torch. Principle of plasma cutting means to focus a lot of. Section 2 introduction to plasma cutting plasma cutting basics what is a plasma. The temperature of the plasma is in excess of 20 000 c and the velocity.

Arc discharge heat forms working gas into the plasma state of high temperature. This increases the temperature and velocity of the plasma emanating from the nozzle. 4 minutes of plasma cutting is working and 6 minutes is necessary for it to cool down. A plasma is a state of matter like a solid liquid or gas.

Plasmorez with own hands. Is passed through a small chamber in which a high frequency spark arc is maintained between the tungsten electrode cathode and the copper nozzle. Working principle of plasma arc machining the principle of plasma arc machining is shown in the figure. This high temperature plasma jet melts the material of the workpiece.

And the cutting object material is fused to be cut. Adding heat to material causes the molecules in it to vibrate or move more quickly. 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. In a plasma torch known as the gun or plasmatron a volume of gas such as h2 n2 02 etc.
