Abstract
A vehicle exhaust system is provided that includes a first exhaust member having an end that includes an enlarged section. A second exhaust member is sized to receive a portion of the first exhaust member. The enlarged section of the first exhaust member has an outer diameter that is larger than an inner diameter of at least one section of the second exhaust member for creating an interference condition between the first and second exhaust member to prevent axial movement of the first exhaust member in at least one axial direction. The first exhaust member is secured to the second exhaust member by magnetic pulse welding.
Claims19
A vehicle exhaust system comprising:
- a first exhaust member having an end that includes an enlarged section;
- and
- a second exhaust member sized to receive a portion of the first exhaust member, the enlarged section of the first exhaust member having an outer diameter that is larger than an inner diameter of at least one section of the second exhaust member for creating an interference condition between the first and second exhaust member to prevent axial movement of the first exhaust member in at least one axial direction, and the first exhaust member is secured to the second exhaust member by magnetic pulse welding.
A method for coupling components of a vehicle exhaust system, the method comprising the steps of:
- providing a first exhaust member;
- inserting the first exhaust member within a second exhaust member;
- extending the first exhaust member through the second exhaust member until a respective portion of the first exhaust member is aligned with a respective portion of the second exhaust member;
- and
- securing the first exhaust member to the second exhaust member using magnetic pulse welding wherein a section of the first exhaust member creates an interference condition with a section of the second exhaust member for preventing axial movement in at least one axial direction.
