Abstract
A frictional weld joint couples first and second body portions of an article together. The frictional weld joint comprises a first bead extending from the first body portion of the article and a second bead extending from the second body portion of the article. The second bead has an interior stem and an exterior stem space from the interior stem defining a cavity therebetween. The first and second beads are placed in contact with each other with the centerline of the second bead offset from the centerline of the first bead. A force is applied to either the first or second body portions to generate friction between the first and second beads to plastically displace the first and second beads. The force is removed for fusing the first and second beads together to couple together the first and the second body portions of the article.
