Plasma Arc Machining Mech4study

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. Today plasma retains the original advantages.

Plasma arc machining mech4study. Plasma arc machining in this article we have to discuss plasma arc machining how it works and its application and main advantages and also disadvantages of this process. Difference between up milling and down milling 6. Metal cutting or machining. Types of milling machine 7. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch. It is a gas shielded metal arc welding which uses the high heat of an electric arc between a continuously fed consumable electrode wire and the material to be welded. Today we will learn about plasma arc welding principle types working equipments application advantages and disadvantages with its diagram. The term plasma as employed in physics means ionized particles. These gases form a shield which does not allow any oxygen and other reactive gases into the weld zone. The main difference between paw and tig is that the electrode is situated inside the torch in paw. It heated the gas at 30000 fahrenheit and converts it into plasma which attack the welding area. In thisntype of welding a metal rod is used as one electrode while the work being welded is used as another electrode. The shielded gases like argon helium is supplied through pressure valve and regulating valve to the welding torch. That means we get the plasma state that we wanted for plasma arc machining. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path.

These gases also create plasma which increases heat capacity of electric arc thus increases welding ability. Now this plasma is targeted towards the workpiece with a high velocity and the machining process starts. Main parts and working 5. This virtually a mixture of free electrons positively. When a flowing gas is heated sufficiently high temperature to become partially ionized it is known as plasma. Plasma arc welding is much similar to gas tungsten welding. Lathe machine main parts operations and working 3. 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 welding is a liquid state welding process in which the metal to metal joint forms in molten state. 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. The hot ionized gases are known as plasma. Shaper machine main parts operation and working 4. Difference between orthogonal and oblique cutting 2. Metal is transferred through protected arc column to the work. In this welding process arc is generate between tungsten electrode and work piece.

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