Abstract

A two-dimensional numerical model is developed to describe the arc characteristics in two-electrode gas tungsten arc welding. The influence of different welding current, shielding gas, and shielding gas flow rate is investigated. The arc characteristics are analyzed by studying the distributions of physical quantities including arc temperature, electric potential, and total heat flux on the workpiece. The simulated results reveal that a higher arc temperature value is obtained in helium arc than in argon arc. For obtaining high arc temperature, there is an optimum range for shielding gas flow rate and too high or too low is not appropriate. In addition, the increase of welding current results in the increase of the maximum arc temperature, electric potential, and total heat flux. To validate the accuracy of simulated results, welding experiments are performed and the arc temperature is calculated by the spectral signal of arc plasma. The simulated results are compared with the experimental ones and there is a good agreement.
