A platform Smart Scalpel system using rapid real-time feedback for effecting laser treatment. The coupling electrode is composed at least of one thin wire, which starts from the zone at the edge of the glazing, is conducted over the surface covered by the cladding, and is returned to the zone of the edge with at least one fold, so that the two ends of the wire are situated in the zone of the edge of the glazing. The powder coatings can be obtained via a grinding-classification process or an agglomeration process.
