Numerical Modelling of a Cutting Arc Torch
(Jan Awrejcewicz. INTECH, 2014-02-14)
Plasma cutting is a process of metal cutting at atmospheric pressure by an arc plasma jet,
where a transferred arc is generated between a cathode and a work-piece (the metal to be
cut) acting as the anode . Small nozzle ...
Numerical modeling of the gas breakdown development in the space–charge layer inside the nozzle of a transferred arc torch
(2012)
Double–arcing is a phenomenon that occurs when a transferred arc, flowing inside an
electrically insulated nozzle, breaks into two separate arcs: one that connects the cathode with
the nozzle, and another that connects ...
Interpretation of Voltage Measurements in Cutting Torches.
(2015)
Anode-cathode and nozzle-cathode voltages, plenum pressure and gas mass flow measurements in a
low current (30 A) cutting torch, operated with oxygen gas, are used as inputs for an electrical model coupled
to a simplified ...
