Gases for Gas Plasma Arc Welding (FCAW)
Company : United States Welding Inc
UMDC Code : 452924
The physical configuration of PAW requires the use of two gases, a "plasma" or orifice gas and a shielding gas. The primary role of the plasma gas, which exits the torch through the center orifice, is to control arc characteristics and shield the electrode. The shielding gas, introduced around the periphery of the arc, shields or protects the weld. In many applications, the shielding gas is also partially ionized to enhance the plasma gas performance.
