Abstract
Abstract A housing part, which can be firmly joined to another housing part for the formation of a housing of a radial flow compressor, in particular a turbocharger. At least one open or closed channel portion is provided in each housing part so that when the housing parts are joined a channel system is formed which runs between the two housing parts. A free-flowing and hardening compaction material, such as an adhesive or a thermoplastic polymer, is inserted into the channel system for the formation of a firm bond between the two housing parts.
