Double Plasma Arc Machining

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. For arc cutting plasma can also be defined as an electrically heated gas stream.

The plasma arc process has always been seen as an alternative to the oxy fuel process.

Double plasma arc machining. 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. Plasma arc machining pam plasma arc machining is a nontraditional thermal process. The ionized gas by definition can then freely exchange electrons between atoms. 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. The term plasma as employed in physics means ionized particles. Active gas welding unit 6. The gas stream is heated to such high temperature that it becomes ionized. 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 unit you will be introduced to plasma arc cutting and the safety precautions required when using plasma arc cutting equipment. 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. Oxy fuel cutting and unit 7 plasma arc cutting. 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 cutting process is illustrated in fig. The basics of plasma cutting. Plasma cutting is used in cutting and gouging.

Today plasma retains the original advantages. Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw. Module 2 thermal processes unit 1 introduction to thermal processes and safety unit 2 introduction to oxy acetylene welding unit 3. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. Understanding the basics of plasma arc cutting and plasma arc gouging will help welding operators be more successful with these techniques. A double arc is a condition which allows the nozzle to stay.
