Method of welding, by using for example friction stir welding, surfaces with polymers sealant and welded structure

Aircraft components, such as assembly 10, for example to form a lap joint between the inner surface of the outside sheathing reinforcement 14 and part 12, using a friction stir welding (FSW) is formed by a weld joint. Monomer sealant / adhesive agent, such as being applied to a surface for the sealing agent layer 24 are combined, the welds 16 and 18, the part 12 is the fluorine-containing coating, such as an elastomeric joint surface welding for sealing is formed in order to prevent corrosion of It is suitably cured by elevated temperatures of the process. Additional heat for curing can be made by a laser 30 or the induction heater 30.Welding, aircraft, reinforcing materials, components, friction stir welding, a sealant
