On the dynamics of the space-charge layer inside the nozzle of a cutting torch and its relation with the “non-destructive” double-arcing phenomenon
(2011)
Experimental observations on the plasma dynamics inside the nozzle of a 30 A oxygen cutting torch
operated at conditions close to the double arcing are reported. It is employed a technique previously
developed in our ...
Experimental Characterization of a Low-Current Cutting Torch.
(2004)
An experimental characterization of a low-current (30-40 A) cutting torch is presented. To avoid contamination
of the plasma arc by removed anode material, a rotating steel cylinder was used as the anode and the arc ...
Numerical investigation of the double-arcing phenomenon in a cutting arc torch.
(2014)
A numerical investigation of the double-arcing phenomenon in a cutting arc torch is reported.
The dynamics of the double-arcing were simulated by using a two-dimensional model of the gas
breakdown development in the ...
On the Double-Arcing Phenomenon in a Cutting Arc Torch.
(2011)
Transferred arc plasma torches are widely used in industrial cutting process of metallic
materials because of their ability to cut almost any metal and the very high productivity that
can be achieved with this technology ...
