Plasma Arc Welding:
It is an electric arc welding process which employs a high temperature constricted arc or plasma jet to obtain the melting and joining metal. In fact, the term “plasma” refers to a gas which is sufficiently ionized to conduct current freely. A conventional welding arc is an example of a plasma. A plasma jet is created when the arc is passed through a constricted nozzle. Due to this constriction, the plasma jet takes a narrow, columnar shape having properties ideal for welding.
