Numerical Simulation Study of Consumable Electrode Melting Process in Electro-Slag Remelting Ingots

Advanced Materials Research, 2011
Electro-slag remelting (ESR) is a kind of special metallurgy techniques to produce high quality alloy materials. The interface of electrode and slag is the energy entrance of entire system in the remelting process.

Consumable double electrode with a single arc GMAW

International Journal of Advanced Manufacturing Technology, 2013
Double-electrode gas metal arc welding (DE-GMAW) was developed to control the heat input to the work piece when the filler wire deposition rate was increased. Consumable DE-GMAW was developed to enhance the welding productivity by replacing the non-consumable electrode in DE-GMAW with a consumable electrode.

Pressures and Consumable-Electrode Arcs

Journal of Vacuum Science and Technology, 1971
An investigation of arc zone pressures during CEVAR (consumable-electrode vacuum-arc remelting) experiments has shown that pressure differences and gradients within furnaces are functions of pressure itself, electrode composition, and the degree of arc-zone confinement.

Technology for Electroslag Remelting with Rotation of the Consumable Electrode

Metallurgist, 2001
It is known that metal which is produced by the method of electroslag remelting (ESR) has service properties superior to those of metal made by open refining and casting. This can be attributed to the better conditions which exist for refi ning in the specially chosen slag and for the crystallization of the metal in the case of ESR.

Electrode voltage in the consumable-electrode arc system

Journal of Physics D: Applied Physics, 1972
In a consumable-electrode arc system the variable portion of the wire electrode between the current pick-up point and the electrode-arc interface (the `electrode stickout') forms an important resistive part of the arc circuit. An approximate relation for the voltage fall along the stickout is calculated in terms of the arc current, the electrode feed ...

Self-regulation of the arc in consumable electrode welding

Welding International, 2015
The characteristic features, criteria and algorithm of the currently available method of self-regulation of the arc in mechanised arc welding with a constant consumable electrode feed rate are investigated. The main problem is that when it is necessary to reduce the welding current, for example with an increase of the thickness of the welded edges or ...

Heat transfer in an electrode during arc welding with a consumable electrode

Journal of Physics D: Applied Physics, 1998
The heat balance of the solid part of the electrode during arc welding with a consumable electrode is considered. Solution of the heat conduction equation makes it possible to obtain a relation between the droplet temperature, the wire feed rate and the electrode extension.

Consumable-electrode vacuum arc melting

JOM, 1958
Demands for new metals and alloys of higher purity are increasing the importance of vacuum melting in general and the consumable-electrode process in particular. Herein is a report on this phase of vacuum metallurgy, by a member of one of the leading European firms in the field.

Consumable Electrode Melting of Reactive Metals

JOM, 1960
Consumable electrode melting of reactive metals was developed because conventional melting methods proved inadequate. Purification of these metals as a function of temperature and pressure is examined, and the problem of the resulting coarse grain size is considered.
