Abstract
A suspension component for a vehicle includes a cast iron body, a high strength steel tube and an adapter ring. The adapter ring includes a protrusion engaged with a face of the cast iron body. The protrusion is heated to a plasticized state as a capacitor is discharged through the protrusion and the face. The adapter ring is welded to the body upon cooling of the adapter ring. The high strength steel tube is fixed to the adapter ring.
