<p>The sheet metal component such as shell manifold for an exhaust gas system, comprises a body (2) consisting of two tubular shells (3, 4) connected with one another along abutting joints (8, 9), and a pipe (5) connected with the shells using a welding seam (11). The two shells form a connection area (10) outwardly placed at the pipe. The abutting joints are closely arranged to one another and extend the shell in the connection area. The two shells are protruded or spaced in the connection area over a longitudinal end of the abutting joints in the longitudinal direction of the pipe. The sheet metal component such as shell manifold for an exhaust gas system, comprises a body (2) consisting of two tubular shells (3, 4) connected with one another along abutting joints (8, 9), and a pipe (5) connected with the shells using a welding seam (11). The two shells form a connection area (10) outwardly placed at the pipe. The abutting joints are closely arranged to one another and extend the shell in the connection area. The two shells are protruded or spaced in the connection area over a longitudinal end of the abutting joints in the longitudinal direction of the pipe. The front side edge comprises a symmetrical flow at the two shells in the longitudinal end of the joints. The distance between the two shells increases with an increasing distance of the longitudinal end of the joints. The two shells are formed in the connection area so that a tangent runs at the flow of the front side edge and the flow of the front side edge has an arc section. The shells protrude one-third of a diameter of the pipe over the longitudinal end of the joints. Another pipe is inserted into the pipe and is connected with an axial end of the outside pipe using a circular welding seam, where the axial end is formed parallel to the flow of the front side edge. The both welding seams are arranged as two-sheet metal seam or three-sheet metal seam.</p> |
