Patent ID: 7759597

Claim:
A method for manufacturing a gas generator ( 1 ) comprising the following steps: a) providing a tubular body ( 10 ) having a circumferential wall ( 12 ) with an opening ( 14 ), b) providing a housing part ( 16 ) having an attachment end ( 26 ), wherein a geometry of a proximate rim ( 20 ) of the opening ( 14 ) and a geometry of the attachment end ( 26 ) are coordinated such that a first contact region encircling the opening ( 14 ) and a second contact region ( 28 ) on the attachment end ( 26 ), which is circumferentially closed, are formed, wherein the first contact region is formed as a contact edge ( 22 ) by means of providing the rim ( 20 ) of the opening ( 14 ) with a chamfer at least in sections, such that the contact edge ( 22 ) is situated in a plane that is perpendicular to a radial direction (r) of the tubular body ( 10 ) and, with respect to the exterior surface of circumferential wall ( 12 ), has varying distances from the exterior surface along the circumference of opening ( 14 ), c) thereafter, placing the housing part ( 16 ) onto the body ( 10 ) such that the contact edge ( 22 ) is in contact with the second contact region ( 28 ) within said plane, and d) joining the tubular body ( 10 ) and housing part ( 16 ) to each other by capacitor discharge welding.
