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

The heat balance of the solid part of the electrode during are 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 Fate and the electrode extension. Comparison of the droplet temperature obtained in this way with the measured droplet temperature showed good agreement Analysis of experimental data has shown that the droplet heat content primarily depends on the wire feed rate.
