Beschreibung
Zusammenfassung:	The present invention is related to a method for applying a coating (4) on a substrate (1), comprising the steps of: - scanning a laser beam (2) along a line on the surface of said substrate, - supplying a coating forming material from a supply system (3), said system moving along the same line as the laser beam but coming up behind the laser beam, so that the coating forming material is deposited on a spot which has previously been heated by the laser beam to a temperature above the melting temperature of the coating forming material, wherein substantially no physical contact occurs between the laser beam and the coating forming material. Preferably, the method further comprises a second step of scanning the surface a second time with said laser beam, without adding coating forming material during the second step.
