PCT No. PCT/EP91/02232 Sec. 371 Date Mar. 16, 1993 Sec. 102(e) Date Mar. 16, 1993 PCT Filed Nov. 26, 1991 PCT Pub. No. WO92/11163 PCT Pub. Date Jul. 9, 1992.A bearer joint for a vehicle bodywork, and in particular a longitudinal front bearer joint, and a process for placing an aluminum bearer on the bearer joint in the vehicle bodywork. The bearer joint comprises a cast aluminum connector for joining together a first forward bearer and a second adjacent bearer. The connector includes a tubular aluminum recess for receiving the rearward end of the first aluminum bearer which is fixed thereto by a transverse weld seam at the front receiving edge of the recess. To replace a damaged front bearer, a ring cut is made to the outer wall of the aluminum recess at a distance from the forward receiving edge corresponding to the zone of thermal influence of the heat affected zone adjacent the weld. A damaged front bearer is then withdrawn from the recess and replaced by a new front bearer which is also welded to the new forward cut edge of the aluminum recess. In this way the front bearer is replaced without compromising the original strength of the bearer joint. The depth of the aluminum recess is sufficiently deep to permit a desired number of repetitions of the repair procedure and still provide for a sufficient depth to ensure a positive locking engagement of the front bearer within the recess.
