Plasma Arc Machining Types

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 we will learn about plasma arc welding principle types working equipments application advantages and disadvantages with its diagram.

Air plasma arc cutting various type of plasmaarc cutting air plasma arc cutting was introduced in early 1960s for cutting mild steel.

Plasma arc machining types. Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw. The plasma arc process has always been seen as an alternative to the oxy fuel process. 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. Now this plasma is targeted towards the workpiece with a high velocity and the machining process starts. What types of materials are cut when using the least commong type of plasma arc cutting which is nontransferred arc process. That means we get the plasma state that we wanted for plasma arc machining. The plasma arc cutting process is illustrated in fig. Plasma arc cutting 1 plasma arc cutting meng 439 dr. Process can also be used to cut stainless. A plasma cutting machine cutting the internal sections of a metal part. Oxygen in the air provides additional energy from the exothermic reaction with molten steel boosting cutting speeds about 25 percent. 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 plasma arc machining is a nontraditional thermal process. Gaafar prepared by eng. Plasma arc welding is a liquid state welding process in which the metal to metal joint forms in molten state.

The hot ionized gases are known as plasma. Plasma can be defined as a superheated electrically ionized gas. Pac is a thermal material removal process that is primarily used for cutting thick sections of electrically conductive materials. The workpiece in the transferred arc process what is part of the electrical circuit as in other arc processes. Conventional plasma arc cutting 13. The term plasma as employed in physics means ionized particles. 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 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.
