A two-piece flexplate assembly having a ring gear welded to a central plate using a capacitor discharge welding process. The weld is established between a joining structure defined between the ring gear and the central plate using either an overlap arrangement, a projection arrangement, or a chamfer arrangement.

Flexplates and method for capacitor discharge welding of flexplates

A joint site design for friction welding of a shaft of a hard material with a hub consisting of softer material, wherein the shaft has a tubular shape with an end face being joined to the hub having a connection area with a flat shape formed by a radial shoulder of the hub.

Joint-site design comprising a hub and a shaft or a gear being friction welded

A method for connecting a shaft and a hub, the hub having a first joining portion and a second joining portion for a connection to corresponding joining portions of the shaft. The shaft and the hub are pressed together at contact points in the area of the first joining portions, while the second joining portions are not yet in contact with one another, and a welding current is fed via the contact points of the parts that have been pressed together, so that the contact points fuse. The shaft is pressed into the hub, while the first joining portions are being fused, until substantially a press fit is formed between the second joining portions.
