Abstract: A damper, such as a vehicle shock absorber, and a method for attaching a ring to a base cup of a damper. The method includes the step of autogenously welding the ring to the damper base cup. The damper includes a ring autogenously welded to the damper base cup. In one variation, the ring is continuous and the base cup has a substantially convex surface with an outward projection. In another variation, the ring is split and has an end portion having a tab which projects radially outward. In one implementation, the welding consists essentially of drawn arc welding.

Abstract: A method for attaching parts together includes several steps. The parts are positioned for drawn arc welding the parts together. A drawn-arc-weld ferrule including metal is obtained. The ferrule is positioned for use in drawn-arc-welding together the positioned parts. The ferrule is cooled. The positioned parts are drawn arc welded together using the positioned ferrule. In a first expression of an embodiment, a drawn-arc-weld ferrule includes metal. In a second expression of an embodiment, a drawn-arc-weld ferrule includes separate segments each including metal.

Abstract: A method for attaching parts together includes several steps. A metal-core consumable welding wire is obtained in one step. In another step, the parts (such as a ring and a base cup of a cylinder of a damper, such as a vehicle shock absorber) are positioned to create a joint line for welding the parts together. An additional step includes gas metal arc welding the positioned parts together using the metal core wire at a negative electrical welding potential relative to the parts creating a weldment along the joint line. In one example, during welding, the parts have a positive electrical welding potential, and the wire is electrically grounded.
