Plasma Arc welding ( PAW )

Keterangan

      Plasma arc welding (PAW) is an arc welding process that melts and joins metals by heating them with a constricted arc established between a tungsten electrode and the metals, as shown in figure aside. It is similar to GTAW, but an orifice gas as well as a shielding gas is used. As shown in figure aside, the arc in PAW is constricted or collimated because of the converging action of the orifice gas nozzle, and the arc expands only slightly with increasing arc length . Direct-current electrode negative is normally used, but a special variable polarity PAW machine has been developed for welding aluminum, where the presence of aluminum oxide films prevents a keyhole from being established.
