Plasma Arc Machining Details

The electric arc is formed between an electrode which is usually but not always made of sintered tungsten and the workpiecethe key difference from gtaw is that in paw by positioning the electrode within the body of the torch the plasma arc can be separated from the shielding gas envelope. Manufacturer of cnc plasma cutting machines heavy duty plasma cutting machine stainless steel plasma cutting machine cnc plasma cutting machine and cnc underwater plasma cutting machine offered by pro arc welding cutting systems private limited pune maharashtra.

This channel is formed by faculty from bit to enhance the knowledge of students towards technical and fundamentals this video explains plasma arc machining pam in details with explanation of all.

Plasma arc machining details. Contents 2 introduction working principle of pam process details of pam applications of pam advantages of pam process disadvantages of pam process various types of pam processes conclusion references. A plasma cutter will use this electrically conductive gas to transfer energy from a power supply to any conductive material resulting in a cleaner faster cutting process than with oxyfuel. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw. Now this plasma is targeted towards the workpiece with a high velocity and the machining process starts. 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. The plasma arc formation begins when a gas such as oxygen nitrogen argon or even shop air is forced through a small nozzle orifice inside the torch. Plasma arc machining process diagram application advantages and disadvantages. That means we get the plasma state that we wanted for plasma arc machining. 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. The term plasma as employed in physics means ionized particles. Plasma arc machining pam plasma arc machining is a nontraditional thermal process. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. By rajnish bhusal department of mechanical engineering ritm 2. Called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch.

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.
