Method and device for welding arc ignition for arc welding apparatus

6156999
  • Method and device for welding arc ignition of an arc welding apparatus providing a reduced level of high frequency disturbances. A welding electrode and a workpiece are connected with a welding power source and to at least two additional high voltage power sources. A short a periodic high voltage pulse is transmitted from the first high voltage power source to a gap present between the welding electrode and the workpiece, to break down the air present between the welding electrode and the workpiece, and to create a current conducting duct there between. The current output of the high voltage power source is restricted in amplitude and rate of rise. The short non-periodic high voltage pulse is superimposed by another, long, high voltage pulse from the second high voltage power source. The long pulse has a current rate of rise not exceeding that of the short pulse, and the open circuit voltage of the second high voltage power source is lower than that of the first high voltage power source. A stretched pulse appears, and the duration of the current discharge increases. The current conducting duct is heated, its electric resistance decreases and an arc is ignited. When the voltage in the current conducting duct decreases to a value less than that of the open circuit of the welding power source, the current starts flowing through the welding electrode and arc to the workpiece, resulting in a welding arc burning from the welding power source.

Combined laser and plasma-arc processing torch and method

6388227
  • A combined laser and plasma-arc Welding torch, Which joins features of separate laser and plasma-arc Welding devices in a single tool. A laser beam is directed by an optic system to be co-linear with the central axis of a plasma-arc torch. The laser beam passes through a group of electrodes, Whose longitudinal axes are disposed at acute angle to the torch central axis on the generatrix of a cone, the apex of Which lies on the torch central axis close to the section plane of a constricting nozzle, and the base of Which faces the main body of the torch. The distance between the central axis and the closest point of the electrode is less than the laser beam radius in a section Which is perpendicular to the central axis and passes through this closest point. The distal ends of the
  • electrodes are provided With heat accumulating bulbs and mechanism for individual protection by delivering a separate gas. The electrodes may be cathodes both, anodes, or, cathodes and anodes. The Welding torch may be additionally provided With a mechanism for additional constricting and stabilization of a plasma jet. Such a mechanism includes grooves arranged on the conic outer surface of the constrict ing nozzle and also on the opposite conic surface, Which is
  • immediately adjacent or spaced from the constricting nozzle surface. Gas is forced through a chamber having the electrodes and nozzle at the chamber bottom end. Electrodes heated by the laser radiation cause the gas to be ionized, forming a plasma-arc in the constricting nozzle. The laser beam passing through the nozzle comes to a focus and interacts With the plasma-arc formed between the electrodes and a Workpiece. The resulting interaction between the plasma-arc and the laser beam forms a plasma-laser discharge Which acts to additionally constrict the laser beam
  • and plasma-arc, causing an increase in the energy density of the Welding spot formed on the Workpiece.

Interaction between plasma streams and the diverter in the thermal phase of disruption

Plasma Physics Reports; Journal Volume: 19; Journal Issue: 8; Aug 1993;
  • The physical processes are considered which are associated with the interaction between powerful streams carrying energy to the scrape-off layer along field lines when disruption occurs and the diverter plates. It is shown that for all materials (W, Mo, C,...) viewed as candidates for diverter-plate constituents, the erosion that takes place in a single disruption is small, with depth of a few microns. The high efficiency with which the diverter surface is screened from the incoming energy flux by the open-quotes vapor cushion close quotes plasma forms in evaporation is confirmed. The shielding factor, defined as the ratio of the energy input to the energy expended in vaporization, may reach 100% for power fluxes W > 10 MW/cm. More than 90% of the incident energy is reradiated by the vapor plasma backward with temperature T=3=10 eV. The difference in the physical processes arising when the interaction involves material with large (A>100) and small (A<10) atomic weights is examined.

Interaction of a Hot Plasma Flow with a Divertor Plate during a Tokamak Plasma Disruption

FUSION TECHNOLOGY 1992, Proceedings of the 17th Symposium on Fusion Technology, Rome, Italy
  • Dense hydrogen plasma streams from plasma guns are often used for studying the behaviour of divertor materials under simulated tokamak disruption conditions. In such experiments rather high target plasma temperatures are observed. To understand this the interaction of an intense high density hot plasma stream with a target material was modeled. During beam deposition a vapor cloud is formed. Its density can decrease below 1017cm−3due to the vapor expansion. In this case a pure beam plasma layer can be formed in front of the vapor cloud having comparable density. The impinging plasma beam is converted into thermal energy of this layer, resulting in a rather high temperature of the layer. The energy is transported into the target vapor cloud by electron heat conduction. Such a process can play an important role in modeling the stream target interaction by a dense plasma flow. Results for a simplified analytical model and results of first numerical calculations using the particle-in-cell method are presented

2D Simulation of Plasma Motion in Impulse Accelerator with curvature electrodes, I.S Landman, ...

Kurchatov Atomic Energy Institute Preprint
  • 2-D MHD calculation of coaxialplasma gun with curve electrodes is carried out. It is shown, that during acceleration towards axis of symmetry the main reason of break-down of plasma ring is instability by Relay, and along axis that is instability due to nonuniform distribution of magnetic field. Influenses of diffusion of magnetic field and viscosity are taken into consideration in code.
