ABSTRACT:
The system comprises: a distance sensing device for sequentially acquiring, during the welding process or before it, individual transverse profiles of the welding gap by gauging its various depths; electronic units for parametrically reconstructing, by combined numeric and vector calculation, the parametric and topological features of the welding gap starting from the various depths acquired by gauging points; electronic circuits that are adapted to compare the features of the acquired welding gap profile and the stored features of the profile of a corresponding nominal ideal welding gap and to infer corresponding data for varying the parameters of the welding process; and control subsystems using, selectively or in combination, one or more of the variation data to adapt corresponding welding parameters.
