Device for the relative rotation of two tools (welding torches) with respect to a component of an exhaust system of a vehicle engine, around a first and a second axis of the component, parallel to each other and eccentric, for completing the same with the butt welding of two pipes located along the first and second axis; the device includes a support cradle with axial symmetry for the component, within which the component can be set with its first axis coaxial with an axis of rotation of the cradle; means for rotating the cradle around its axis of rotation by at least 360°, first support means for a first tool located at a first radial distance from the first axis, second support means for a second tool located at a second radial distance from the second axis, means for rotating the second support means around the second axis, along a circumference having as its radius the second radial distance, and transmission means for transmitting a synchronised movement of rotation from the means for rotating the cradle to the means for rotating the second support means. |
