PCT No. PCT/EP91/02116 Sec. 371 Date Apr. 20, 1993 Sec. 102(e) Date Apr. 20, 1993 PCT Filed Nov. 8, 1991 PCT Pub. No. WO92/11169 PCT Pub. Date Jul. 9, 1992.The invention concerns an improved welded joint in a vehicle bodywork for connecting two mutually perpendicular extruded aluminum pieces such as a longitudinal bearer or sill and an upstanding B post. According to the invention, the bottom end of the B post is inserted within an opening in the sill for a positive locking engagement and includes a transverse weld seam which connects the B post to the opening along a first outward facing wall portion of the B post. In addition, a connecting member in the form of a flat plate is placed along the inward facing wall of the B post and is joined at a vertical side edge to the B post by a first weld seam and has a bottom side edge oriented flush with the upper sill surface in the lengthwise direction of the sill and is joined thereto by a second weld seam. The welded connection of the two mutually perpendicular aluminum frame members through the use of a separate plate provides a simple and economical solution which ensures a positive and strong connection in the transverse direction of the vertical member and overcomes the problems of material weakening from thermal influences of a completely surrounding transverse weld connection.
