  • Patent number: 4403639
    Abstract: A stud arrangement on casehardened studded chains for motor vehicles, wherein the studs consist of a steel body which is permanently welded to a chain link and provided with a centrally disposed hard metal pin. The hard metal pin is inserted into the steel body such that it is covered on all sides by steel material of a thickness which at least corresponds to the casehardening penetration depth. In a method for producing such studded chains, an inwardly converging blind hole is cut out from one end of the steel body. The hard metal pin, of a shape corresponding to the conical hole, is forced into the hole, the pin being shorter than the blind hole so that a skirt is formed outside the pin. The edge of the skirt is beveled, and the steel body with the metal pin therein is joined to the chain by resistance welding in a machine for welding studs onto chain links, the body with the pin being moved gradually toward the chain link as the beveled edge melts and flows radially outwards.
