摘要 1. A process for manufacturing a conduit for fluid or gaseous media, in particular a distributor conduit provided with a connection opening with outlet openings arranged in a conduit wall, especially for internal combustion engines, wherein the conduit, which is made from at least one sheet metal strip, is formed by laser- or electron beam welding of abutting ends facing each other without a gap, characterised in that the distributor conduit is formed from two parts of sheet metal strips equipped with flanges, wherein, at least in one of the sheet metal strips, a crease is arranged to run in a longitudinal direction between longitudinal flanges, which is constructed in both end regions of the sheet metal strip in each case to end at a distance from the end delimitation, leaving transverse flanges which connect the longitudinal flanges, and that the abutting ends of the flanges of both parts are clamped against each other without a gap for a welding of the parts in the abutting ends by means of a laser- or electron beam directed transversely to the abutting ends.
