A process for the preparation of a corrosion-resistant connection of the metallic components, in particular of aluminum for the cell of air - or spacecraft by means of spot welding

摘要

Method of producing a corrosion-resistant joint between metallic structural elements by spot welding, the method being characterised by the steps: - pretreatment of the joining surfaces (4', 5') for - the spot-welding operation, and - the adhesive application of anti-corrosive layers (8), as well as - degreasing, - rinsing - pickling, - application of a layer (8) of sealing compound at least on one side to the joining surfaces (4, 5) of one of the structural elements (4, 5), - tacking of the structural elements (4, 5), - spot-welding operation with - setting of a defined electrode pressure for obtaining metallically bright joining-surface sections in the area of the electrode pressure point (10), - current supply for producing the weld spot (11), and - hardening of the sealing compound (8).
