Abstract: A process is provided for welding an assembly of a first tubular component and a second tubular component, the first and second tubular components having first and second cylindrical portions, respectively. The process uses a pressing jig, a pressing tool, a welding jig and a welding head. The process includes: positioning the first tubular component with respect to the pressing jig; clamping the first tubular component against the pressing jig; freely fitting the second cylindrical portion into the first cylindrical portion, the two cylindrical portions being substantially coaxial; placing the second component with respect to the first cylindrical portion and the pressing jig; tightening the second tubular component against the pressing jig; aligning the two fitted cylindrical portions with the pressing tool; and pressing by plastic deformation the first and second cylindrical portions. The first and second pressed tubular components form a rigid assembly, with the two fitted and pressed cylindrical portions defining a fitting and a joint. Additional steps include: positioning the rigid assembly with respect to the welding jig; clamping the rigid assembly against the welding jig; and welding by positioning and orienting the welding head repeatably with respect to the fitting and the joint, where the rigid assembly is positioned with respect to the welding jig along one or more surfaces belonging exclusively to the first component in the pressed state.

Abstract: A machine comprises a tool for pre-positioning of a body of an exhaust component and a fitting tool having a passage converging from a large opening to a small opening. An actuator device is configured to push the body along a main axis of the machine toward a cover of the exhaust component through the converging passage.
