Plasma Arc Machining Arco Electrico Plasma Fisica

Plasma arc machining is a metal removal process in which the metal is removed by focusing a high velocity jet of high temperature 110000c to 300000c ionized gas on the workpiece.

Applications of plasma arc machining process. Decommissioning experience shows that the main field of application for the plasma arc process is cutting material up to 40 mm thickness with hand held torches especially tubes pipes and fittings made out of steel. What is plasma arc machining. The plasma arc welding and cutting process was invented by robert m. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. Application of plasma in cutting technology author. Plasma arc machining process diagram application advantages and disadvantages. 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. When the pilot arc touches the workpiece flying cutting flying. The plasma arc cutting process is illustrated in fig. The plasma arc process has always been seen as an alternative to the oxy fuel 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. Gage in 1953 and patented in 1957. 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. The term plasma as employed in physics means ionized particles.

Plasma arc machining 1. Plasma arc machining pam plasma arc machining is a nontraditional thermal process. Plasma torches for manual use are quite small and easy to handle whereas greater wall thicknesses require a mechanical guide. Called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch. Parts working principle advantages application and more. The process employs two inert gases one forms the arc plasma and the second shields the arc plasma. 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. 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. This low energy pilot arc prepares by ionization in parts the way between plasma torch and workpiece.
