A surface heating device for regional heating of a part-zone of the fibre-composite component to be bonded is performed for desorption of contaminants. A sensor array with a plurality of sensors detects contaminants in the gas phase, and a control device ascertains and signals contaminations which are found. An extractor device can be employed to extract machining dust from the fibre-composite component to a desorption device. ## Claims ### Claim at position 1 1-15.
