Plasma Gas Supply Swirl Component
The swirl component of the plasma gas feed stabilizes the arc column through centrifugal forces and increases energy density in the beam center, which prevents the plasma nozzle from burning out.
Physicochemical Mechanism of Action
The plasma gas swirl component creates a rotational movement in the plasma gas flow. These centrifugal forces push the gas particles together at the center and stabilize the arc column by preventing the plasma nozzle from burning out. The swirl effect increases the energy density at the beam center, leading to a more efficient welding process.
Metallurgical Relevance & Welding Risks
Without a stabilized arc column, irregular weld currents and porosity can occur. The burning out of the plasma nozzle can lead to energy loss and reduced weld quality. An optimal swirl component ensures that the arc column remains constant and stable, which increases overall weld quality.
Workshop Practice & Instructions
To set up an effective plasma gas swirl component, make sure the gas flow is correctly adjusted and the rotational movement is kept stable. Regularly monitor the arc column for stability and adjust the swirl component settings as needed. The optimal setting can be found through manufacturer instructions or by experimenting with different gas flow parameters.
