Union for coupling between a pipe conducting exhaust gas and an attachment flange and procedure for the realization of this union.

摘要

The invention relates to a Union for assembling at least one tube (1) of an internal combustion engine, LEADING SEPARATE EXHAUST WITH A retaining bracket (3) THAT IS INTRODUCED IN YOUR feedthrough (7) And welded at its opening edge (4) which is located inside the nozzle (7) WALL feedthrough (6) of the flange (3). ALSO The invention relates to a method for manufacturing. TO FACILITATE A SAFER WAY EASY automation PROCESS FOR PRODUCING THE UNION FOR ASSEMBLY, it INTENDS CONFORM TO THE WALL feedthrough (6) and an axial position defined at least one projection SUPPORT (14) is inserted into the nozzle (7), when the tubing (1), when in insert position axially immediately adjacent to this, to which effect the inner tube wall (17) is closed FLUSH WITH closing edge (16) of the projection (14), THIS COULD ALSO STAND radially inwards.
