Plasma Arc Machining Process

Plasma arc machining pam plasma arc machining is a nontraditional thermal process.

Explain plasma arc machining process. The plasma arc process has always been seen as an alternative to the oxy fuel process. 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 is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. The plasma arc welding and cutting process was invented by robert m. The hot ionized gases are known as plasma. Today we will learn about plasma arc welding principle types working equipments application advantages and disadvantages with its diagram. Filler metal may or may not be added. The process employs two inert gases one forms the arc plasma and the second shields the arc plasma. 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. 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. 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. In this process an inert gas is blown at high speed out of a nozzle. 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 employs a high velocity jet of high temperature gas to melt and displace material in its path. Working principle plasma arc cutting is a very complex process that is used in order to cut steel and other metalsor sometimes other materials using a plasma torch. Plasma arc welding is a liquid state welding process in which the metal to metal joint forms in molten state. The plasma arc cutting process is illustrated in fig. 56 ultrasonic machining 57 chemical machining processes 58 electrochemical machining 59 laser beam machining 510 plasma arc machining 511 summary 512 answers to saqs 51 introduction modern machining methods are also named as non conventional machining methods. Gage in 1953 and patented in 1957.
