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 diagram. Plasma arc machining process diagram application advantages and disadvantages. In plasma cutting is formed when an electric arc heats and ionizes a stream of high pressure gas. The plasma arc cutting process cuts metal by melting a section of metal with a constricted arc. 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. Called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch. Advantages of pam disadvantages of pam applications of pam. A high velocity jet flow of hot ionized gas melts the metal and then removes the molten material to form a kerf. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. That means we get the plasma state that we wanted for plasma arc machining. Now this plasma is targeted towards the workpiece with a high velocity and the machining process starts. 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. 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. The term plasma as employed in physics means ionized particles. Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw. Today plasma retains the original advantages.

Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. Plasma arc machining pam plasma arc machining is a nontraditional thermal process. 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. A fourth state of matter distinct from solid or liquid or gas and present in stars and fusion reactors. 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.
