Abstract: A method and system for monitoring and identifying the quality of a welding performed by a welding machinery on a metallic component, which includes establishing a plurality of classes that describe possible weld defects on the metallic component; identifying a plurality of features that are relative to the functioning of the welding machinery; acquiring the values assumed by the plurality of features during the execution of a current welding on a metallic component; and processing the values assumed by the plurality of features during the execution of the current welding to establish the probabilities of the future outcome of the welding of belonging to each of the classes of the plurality of classes.
