ABSTRACT:
A gas generator housing part is produced of a thin-walled tube having a wall thickness which amounts to a maximum of 10% of a tube external diameter and a minimum tensile strength which amounts to at least approximately 800 N/mm2, and a connecting piece having an external diameter which amounts to between 15% and 40% of the tube external diameter. After aligning the connecting piece radially to the tube such that an end face of the connecting piece faces an outer face of the tube, the tube and the connecting piece are joined by friction welding. A maximum welding time amounts to less than 1 second, preferably less than 0.3 second and a friction depth amounts to less than 80% of the wall thickness of the tube.
