Plasma arc machining nptel. In plasma arc cutting transferred arc mode can machine a only electrically conductive workpiece b only electrically non conductive workpiece c both type of workpiece ans. Nitrogen is used as the plasma gas in a air plasma torch b oxygen injected torch ans. 6 signs and a table duration. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. These methods form a group of processes which removes excess material by various. Plasma arc welding paw is an arc welding process similar to gas tungsten arc welding gtaw. A person doesnt need to be a physicist or chemist to understand the plasma arc. 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. 42fab metal fabrication signage 303851 views.

Today plasma retains the original advantages. Plasma arc machining pam plasma arc machining is a nontraditional thermal process.

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 topic for the thesis writing is the analysis of process parameters of plasma arc cutting using design of experiment techniques. The focus on this project is to obtain an optimum condition setting to obtain maximum mrr and minimum the surface roughness sr.
