ABSTRACT:
A method of forming vehicle wheel rims includes utilizing linear friction welding. A generally planar piece of metal material is placed into a coil position with two ends in abutment. The abutting ends are oscillated or moved, in a generally linear pattern, relative to each other to increase the temperature of the metal at each end. After the temperature has been increased sufficiently, without reaching the melting temperature of the metal, the linear motion is stopped. The ends are then aligned precisely and forced together with an increased axial load. After cooling, the two ends are permanently joined together with an essentially defect-free welded joint.
