Abstract
A bumper assembly includes a bumper beam having a bumper beam surface extending along a bumper plane X and a crash box including a crash box surface extending along a crash box plane Y. One of the bumper beam and the crash box includes an alignment joint to mate the bumper beam and the crash box and dispose the surfaces in abutting and aligned relationship relative to one another for establishing a linear load path extending linearly along the planes X, Y. A method of assembling a bumper assembly includes the steps of mating the bumper beam and the crash box about the alignment joint and connecting the bumper beam and the crash box together along the alignment joint. The step of connecting the bumper beam and the crash box includes friction stir welding the bumper box and the crash box together along the alignment joint.
