A muffler for an exhaust gas system of an internal combustion engine. The muffler has a muffler housing having at least two interconnected housing shells delimiting a muffler interior. Each housing shell has a connecting edge extending away from the muffler interior. The housing shells are mutually connected by material bonding in the region of their mutually adjacent housing shell connecting edges. An insulating arrangement covers at least regions of the inner side of one of the housing shells. The insulating arrangement has an insulating shell with an insulating shell connecting edge extending away from the muffler interior and the insulating shell is arranged with the insulating shell connecting edge between the mutually adjacent connecting edges of the housing shells and is connected by material bonding to the connecting edges of the housing shells in the region of the insulating shell connecting edge.

Muffler

A vehicle, internal combustion engine, exhaust system, housing includes housing shell areas (), which are connected together in a folded connection area (). The folded connection area includes a folded edge area (), extending along a folded edge longitudinal axis (L), and a plurality of spaced apart crimped sections (), which extend essentially at right angles to the folded edge longitudinal axis (L) and away from the folded edge area () and provide intermediate spaces (). Some of the crimped sections (), of one housing shell area mesh with an intermediate space formed between two crimped sections () of another housing shell area and overlap the folded edge area () of the other housing shell area () such that the folded edge area () of the other housing shell area () is held between the crimped sections ().

A method for fastening a metallic bushing () to a metallic component () includes forming a ring-shaped contact surface () on the bushing, forming an opening () in the component and providing a collar () extending circumferentially along the opening in the component and projecting on a mounting side () of the component. The mounting side is brought into contact and pressed in the area of the opening in the component such that the contact surface touches the collar. The bushing () is pressed on the mounting side () of the component in the area of the opening (), so that the contact surface is in contact with the collar under prestress. With the contact surface () in contact with the collar under prestress, the bushing () and the component () are resistance welded together in the area of the contact between the contact surface () and the collar ().
