ABSTRACT --- Adaptive Neural Networks (ANN) can be employed in the
analysis of complex input/output data under industrial conditions, even when
they may present substantial noise. Despite presenting conceptually substantial
mathematical complexity associated with non-linear parametric models that
include transfer equations and respective “training procedures “, ANN are largely
employed under industrial conditions in different engineering areas such as steel
processing, with great success. This work aims at the presentation of the
applicability of ANN in the specific case of the AA6063 and AA6351 extruded
alloys, under different industrial conditions, trying to exemplify its applicability
in process control. Results will be analyzed in terms of the adhesion to the ANN
of the collected industrial data as well as the relevance of each input within the
