Abstract
A method for the repair of an aluminium metal structure that has been damaged involves applying a heat-curable adhesive between faying surfaces of components and curing the adhesive by means of infra-red radiation. An infra-red absorbing coating, such as a black lacquer, is applied to an exterior surface of the structure to be heated, and is effective to confine heat supplied to the desired region and to avoid overheating, both of the infra red lamps and the remainder of the structure.
