1. A method for producing a component with a surface that is suitable for joining of two and more parts, the method comprising:
providing a first component comprising a first surface;
arranging a filler sheet comprising a thermoplastic material on the first surface;
arranging a structuring tool on the filler sheet;
applying mechanical force to the structuring tool to provide a compressive force between the structuring tool and the first surface and applying heat to the filler sheet such that due to the compressive force, the tool is urged into the filler sheet and becomes partially embedded in the filler sheet as the thermoplastic material of the filler sheet melts and such that the filler sheet is attached to the first surface of the first component;
removing the structuring tool from the filler sheet and producing in the filler sheet an outer surface comprising a plurality of protrusions.
