Resumo
The electric arc is the most used heat source in the fusion welding of metallic materials, since it presents an optimum combination of characteristics, as a result, the processes of arc welding have a great industrial importance, being used in the manufacture of the most varied components and structures and in the recovery of many parts. Many factors are observed in the arc, such as the behavior with the tension, its profile (area), emitted luminosity and thermal efficiency, all of which factors will influence the characteristics of the welds produced. Thus, the objective of this work is to evaluate the characteristics of the electric arc of the GTAW welding process. For this purpose, the arc characteristic curves, its profile (where the measurement of its area was sought) and its emitted luminosity were analyzed. In addition, the thermal efficiency and the heat input from the process were also measured with the help of a continuous flow water calorimeter. The results obtained demonstrated a relationship with data observed and disseminated in the literature.
