![عکس صفحه اول مقاله: Effect of process parameters on temperature distribution in twin-electrode TIG coupling arc Effect of process parameters on temperature distribution in twin-electrode TIG coupling arc](/preview/png/5429264.png)
The twin-electrode TIG coupling arc is a new type of welding heat source, which is generated in a single welding torch that has two tungsten electrodes insulated from each other. This paper aims at determining the distribution of temperature for the coupling arc using the Fowler-Milne method under the assumption of local thermodynamic equilibrium. The influences of welding current, arc length, and distance between both electrode tips on temperature distribution of the coupling arc were analyzed. Based on the results, a better understanding of the twin-electrode TIG welding process was obtained.
⺠Increasing arc current will increase the coupling arc temperature. ⺠Arc length seldom affects the peak temperature of the coupling arc. ⺠Increasing arc length will increase the extension of temperature near the anode. ⺠Increasing distance will decrease temperatures in the central part of the arc.
