Abstract: An attachment connection is provided including a thin-walled hose line connected with a carbon-containing attachment part of a carbon-containing iron alloy with a carbon component C >0.5% and a weld connection is provided between the hose line and the attachment part.

Abstract: An attachment connection (1) for connecting thin-walled hose lines (2) to a carbon-containing attachment part (3), in particular made of cast iron, in which the hose line (2) is secured on the attachment part (3) by welding. This makes it possible to achieve an in particular gas-tight connection between the hose line (2) and the attachment part (3) and, in addition to advantageous production costs, this connection is requires only a small amount of installation space, which, for example in the case of the hose line (2) being configured as a bellows, allows an increase in the number of bellows corrugations and thus, with the same amount of installation space, an increase in flexibility associated with a longer service life.
