Correlation methods in cutting arcs
(IOPscience, 2011-05-25)
The present work applies similarity theory to the plasma emanating from transferred arc, gas-vortex stabilized plasma cutting torches, to analyze the existing correlation between the arc temperature and the physical ...
Departures from local thermodynamic equilibrium in cutting arc plasmas derived from electron and gas density measurements using a twowavelength quantitative Schlieren technique.
(2011)
A two-wavelength quantitative Schlieren technique that allows inferring the electron and gas
densities of axisymmetric arc plasmas without imposing any assumption regarding statistical
equilibrium models is reported. ...
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 ...
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 ...
