Abstract
A method for weldbonding at least two work-pieces together includes applying an adhesive to a first surface of a first work-piece, and bringing the first surface of the first work-piece into contact with a surface of a second work-piece. The first work-piece and second work-piece are then friction stir or friction stir spot welded together, and the adhesive is cured. The use of bonding tools to maintain the two work-pieces together during curing of the adhesive is eliminated.
