Abstract
A frictional weld joint couples together first and second body portions of an article. The first body portion has a first nominal wall thickness and a first joint surface. The second body portion has a second nominal wall thickness and a second joint surface. A total bead height is defined between the joint surfaces. A first bead extends from the first joint surface defining a first bead height. A second bead extends from the second joint surface and is coupled to the first bead. A final second bead height is defined between the first bead and the second joint surface. A ratio of the first bead height to the final second bead height is of from about 0.40 to about 1.70. A ratio of the total bead height to at least one of the first and second nominal wall thicknesses is equal to or less than 6.00.
