In order to understand the mechanism of weld bead formation, a relationship between arc welding parameters and weld bead geometry must be established. This relationship is also necessary to forecast penetration variables allowing to optimize welding parameters for particular applications. However, establishing this relationship is a rather difficult problem due to the large number of parameters involved in the process along with the complexity of the process itself. In this regard, many investigators have performed experiments in aluminum using the GMAW processes in an effort to predict weld joint penetration behavior. Other researchers have also study the influence of the welding speed, arc current and arc voltage on the penetration. However, in spite of all this effort, a defined pattern to predict the influence of these parameters on the weld joint penetration for aluminum has not been established. The result of this research is an empirical expression for the prediction of penetration in V-groove joints of aluminum 6063-T5 using the GMAW technique. Also, the influence of these variables on the weld penetration is studied, providing with new evidence in aluminum welding.
