Abstract
An improved method is disclosed for fabricating a clutch cylinder-drum assembly for use in a vehicle drivetrain wherein no additional manufacturing steps are needed to remove weld spatter or weld material from the interior of the clutch cylinder. In a first embodiment, a drum has an annular axially protruding projection which is forcibly positioned against a clutch cylinder. Electrical current is passed through the projecton to create a weld connection securing the clutch cylinder to the drum. A second embodiment uses a laser beam weld to join these components.
