The properties of plasmas generated for the air plasma cutting process have been investigated in this study. The plasma arc cutting process employs a plasma torch with a very narrow bore to produce a transferred arc to the workpiece at an average current density of within the bore of the torch. The energy and momentum of the high-velocity plasma jet generated by the plasma torch melts, vaporizes and removes the metal from the region of impingement of the jet. Measurements have been made of the… 



Scaling Laws for Gas-Blast Circuit-Breaker Arcs during the High Current Phase

A steady state nozzle arc model based on the boundary layer integral method is established and scaling laws are derived. For affinely related nozzles, the solution is uniquely determined by a nozzle

Prediction of properties of free burning welding arc columns

An approximate model is used to predict properties in the current range from 100 to 500 A. Calculations show that a high value of current density at the cathode produces a narrow plasma jet of high

Arc-electrode phenomena

The paper gives a survey of the most important aspect of arc-electrode processes (excluding externally heated cathodes) which concern engineers in a variety of applications. Although it is not

An Experimental Study of Circuit-Breaker Arcs in Nozzles under Clogged Conditions

This paper describes an experimental investigation of airblast arcs in nozzles under clogged conditions. From a suitable computer model of the air supply system and by the use of approximately flat

The Energy Transport, Including Emission and Absorption, in N2-Arcs of Different Radii

Steady, motionless cascaded N2-arcs with tube diameters of 2, 3, and 5 mm are investigated at atmospheric pressure to gain insight into the radiative energy transport for temperatures up to 27,000 K.

Development of a 'Smart' Plasma Arc Cutting System

This paper discusses some performance limiting factors in plasma arc cutting technology. This technology is utilised in the metal fabrication industry for cutting metallic plate and sheet. The main

An Approximate Model for High Current Free Burning Arcs

An approximate model has been developed using an integral formulation to predict the properties of high current free burning arcs, which are characterised by strong self magnetically driven plasma

Characteristics of Radiation‐Dominated Electric Arcs

Temperature profiles of arcs when radiation is the principal energy transfer process have been derived from material functions. Arcs which are optically thin are approximately isothermal or
