The present invention relates to a method for coating a component (1) of a gas turbine or an aircraft engine, in particular for producing a blade-tip armor cladding on a blade of a gas turbine or aircraft engine, in which a coating material is applied to the component with a solder and the component is heated inductively, with at least the solder of the coating material being heated by means of a laser (4) in such a way that solder connection between the component and the coating material is achieved, as well as a corresponding device for carrying out the method.
