TL;DR: In this article, a computational model of the argon arc plasma in gas-metal arc welding (GMAW) that includes the influence of metal vapour from the electrode is presented, and the occurrence of a central minimum in the radial distributions of temperature and current density is demonstrated.

TL;DR: In this article, the influence of different values for the net radiative emission coefficient of iron vapour, which vary by up to a factor of hundred, is examined, and it is shown that these net emission coefficients cause differences in the magnitudes, but not in the overall trends, of the radial distribution of temperature and current density.

TL;DR: In this article, a numerical model of the droplet detachment of a gas-metal arc welding process is presented based on the volume of fluid method and focuses on the detailed description of the interaction between the arc and the anodic wire electrode.

TL;DR: In this paper, the authors present a detailed analysis of thermodynamic properties of mixtures of argon and aluminum, iron and copper vapours at atmospheric pressure, for the temperature range 300 to 30 000 K, for different concentrations of the metal vapours.

TL;DR: In this article, a transient three-dimensional model of an anti-phase-synchronized pulsed tandem gas-metal arc welding process is presented, which is used to analyse arc interactions and their influence on the gas shield flow.
