Abstract Plasma arc cutting (PAC) is an erosion process that utilizes a constricted arc in the form of a high-velocity jet of ionized gas to melt and sever metal in a narrow, localized area. This article discusses the process description, equipment, gases, operating sequence, process considerations, and applications of PAC.

Analysis of plasma arcs in arc-driven rail guns
IEEE Transactions on Magnetics, 1984In this paper we present a relatively simple model for estimating the properties of the arc in arc-driven rail guns. The model assumes that the arc is steady in a reference frame that accelerates with the arc/projectile system, and accounts for the effect of finite rail height on the accelerating force and on the arc properties.

Three-Dimensional Modeling of Plasma Arc in Arc Welding
Heat Transfer, Volume 2, 2006Most previous three-dimensional modeling work in gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW) focuses on the weld pool. Almost all three-dimensional weld pool models are based on the two-dimensional axisymmetric Gaussian assumption of plasma arc pressure and heat flux.

Theory of Magnetic Effects in the Plasma of an Arc
Physical Review, 1939The equations governing electron drift in the presence of a magnetic field are applied to the low pressure uniform positive column plasma. (1) An exponential variation of electron concentration with distance across an arc in a transverse magnetic field, found experimentally, is accounted for quantitatively.

Joining of Duplex Stainless Steel by Plasma Arc, TIG, and Plasma Arc+TIG Welding Processes
Materials and Manufacturing Processes, 20081.4462 duplex stainless steel (DSS) with a thickness of 6.8 mm was joined by plasma arc, Tungsten Inert Gas (TIG), and plasma arc + TIG welding processes. Impact toughness testing was carried out and fractographs were examined by Scanning Electron Microscopy (SEM).
