| Popis: | Various methods of gas-vortex stabilization in plasma torches for metal cutting are investigated. The influence of an angle of plasma-forming gas injection into the nozzle on kinematic characteristics of the plasma jet is shown. The increase in the radial component of the velocity at the output from the swirler makes it possible to increase the uniformity of velocity distribution and the kinetic properties of jet in the zone of influence on the cut metal. For the cutting of the thin sheet metals, it is advisable to use the technology of “narrow-jet plasma”. © 2020 Trans Tech Publications Ltd, Switzerland.
