Types of plasma arc machining. Oxygen in the air provides additional energy from the exothermic reaction with molten steel boosting cutting speeds about 25 percent. Pac is a thermal material removal process that is primarily used for cutting thick sections of electrically conductive materials. Plasma arc cutting 1 plasma arc cutting meng 439 dr. Conventional plasma arc cutting 13. Plasma can be defined as a superheated electrically ionized gas. That means we get the plasma state that we wanted for plasma arc machining. What types of materials are cut when using the least commong type of plasma arc cutting which is nontransferred arc process. Today we will learn about plasma arc welding principle types working equipments application advantages and disadvantages with its diagram. 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 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. 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. Ahmad hassan sayed 2 plasma arc cutting. Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw. 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 plasma arc cutting process is illustrated in fig.

Plasma arc welding is a liquid state welding process in which the metal to metal joint forms in molten state. 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. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. The term plasma as employed in physics means ionized particles. Plasma arc machining pam plasma arc machining is a nontraditional thermal process. Air plasma arc cutting various type of plasmaarc cutting air plasma arc cutting was introduced in early 1960s for cutting mild steel. The workpiece in the transferred arc process what is part of the electrical circuit as in other arc processes. Now this plasma is targeted towards the workpiece with a high velocity and the machining process starts. Process can also be used to cut stainless.
