Correlation methods in cutting arcs
(IOPscience, 2017)
Determination of plasma velocity from light fluctuations in a cutting torch
(American Institute of Physics, 2009-11)
Measurements of plasma velocities in a 30 A high energy density cutting torch are reported. The velocity diagnostic is based on the analysis of the light fluctuations emitted by the arc which are assumed to propagate with ...
Automação da altura da tocha de plasma, em processos de corte metalúrgico
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de EletrônicaTecnologia em Automação IndustrialUTFPR, 2014-02-28)
A conventional cutting plasma equipment was having problems due to the torch height during the cutting process, from the imperfections of the plates, causing wear consumables thus decreasing the useful life and causing ...
Plasma cutting of concrete: Heat propagation and molten material removal from the kerf
(Institute of Electrical and Electronics Engineers, 2019-05)
An experimental investigation of heat propagation in the case of plasma cutting of concrete is reported. The experiments were carried out by using a high-enthalpy nitrogen plasma jet generated in a dc vortex-stabilized ...
On the dynamics of cutting arc plasmas: the role of the power supply ripple
