Plasma Arc Welding. In the transferred-arc mode of the PAW process, shown in Figure lc, the arc is between a nonconsumable electrode and the base metal, in a manner similar to the GTAW process. The unique feature is the flow of inert gas around the electrode and through a restricted orifice, which constricts the arc to form a plasma jet. A second, outer stream of shielding gas protects the molten metal from atmospheric contamination. In the nontransferred arc mode of the PAW process, the arc is between the electrode and the constricting orifice. This mode is used for plasma spraying...

The delta ferrite content of each lot and/or heat of weld filler metal used for welding of austenitic stainless steel code components shall be determined for each process to be used in production. Delta ferrite determinations for consumable inserts, electrodes, rod or wire filler metal used with the gas tungsten arc welding process, and deposits made with the plasma arc welding process may be determined by either of the alternative methods of magnetic measurement or chemical analysis described in Section III of the ASME Code. 

Plasma arc welding and cutting can be of either the transferred or non-transferred arc type. The arc is struck between a non-consumed centre electrode and an annular tube surrounding it through which the gas is emitted. In the transferred arc process, which is applicable only to con-... 

Plasma arc welding (PAW) is also applicable to the welding of titanium and tit um alloys. It is faster than GTAW and can be used on thicker sections, such as one-pass welding of titanium alloy plate up to 13 mm (V2 in.) thick, using square-groove butt joints and the key-hole technique.
