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.

Plasma arc machining steps. Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw. 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 cutting is faster than oxyfuel for cutting steel up to 50 mm thick and is competitive for greater thickness. 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. Plasma arc machining process diagram application advantages and disadvantages. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. 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. The plasma arc cutting process is illustrated in fig. Introduction the plasma arc machining process was introduced to the industries in 1964 as a method of bringing better control to the arc welding process in lower current ranges. Advantages of plasmaarc machining rapid cutting speeds. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. In this part of the series the process fundamentals are described with emphasis being placed on the operating features and the advantages of the many process variants. Plasma cutting achieves speeds greater than those of laser cutting systems for thickness over 3 mm. Today plasma retains the original advantages.

Called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch. 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. The plasma arc process has always been seen as an alternative to the oxy fuel process.
