Plasma In Arc Machining

Now this plasma is targeted towards the workpiece with a high velocity and the machining process starts. Process can also be used to cut stainless.

This channel is formed by faculty from bit to enhance the knowledge of students towards technical and fundamentals plasma arc machining is used for variety of industrial application.

Plasma in arc machining. As the gas comes in contact with the plasma there is a collision between the atoms of a gas and electrons of an electric arc and as a result we get an ionised gas. Here you can see the plasma cutter going up and down using the arc voltage. Conventional plasma arc cutting 13. Just as oxy fuel torches can be used for either welding or cutting so too can plasma torches which can achieve plasma arc welding or plasma cutting. Called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch. The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore copper nozzle. Plasma arc machining pam. We taped a video camera to the gantry on our torchmate cnc plasma cutting table for a ride along while it was cutting. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. Actually all welding arcs are partially ionized plasmas but the one in plasma arc welding is a constricted arc plasma. Pam is a method of cutting metal with a plasma arc or tungsten inert gas arc torch. Air plasma arc cutting various type of plasmaarc cutting air plasma arc cutting was introduced in early 1960s for cutting mild steel. This increases the temperature and velocity of the plasma emanating from the nozzle. The torch produces a high velocity jet of high temperature ionized gas plasma that cuts by melting and displacing material from the workpiece. Plasma arc machining pam plasma arc machining is a nontraditional thermal process.

Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasmatypical materials cut with a plasma torch include steel stainless steel aluminum brass and copper although other conductive metals may be cut as wellplasma cutting is often used in fabrication shops automotive repair and restoration industrial construction and. Oxygen in the air provides additional energy from the exothermic reaction with molten steel boosting cutting speeds about 25 percent. The term plasma as employed in physics means ionized particles. That means we get the plasma state that we wanted for plasma arc machining. Plasma arc machining process diagram application advantages and disadvantages. The plasma arc cutting process is illustrated in fig. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path.
