Abstract
A method for producing welded round and profile chains of chain links that are connected to each other. The chain links for round and profile chains produced by this method include two chain link partial pieces that are connected to each other by friction welding.
Claims18
A method for producing welded round and profile chains made of a plurality of chain links which are connected to one another, the method for joining each chain link of the plurality comprises:
- providing a pair of chain link parts which when paired together having a plane of separation;
- linear friction welding the two chain link parts together along a welding plane lying in the plane of separation of said chain link parts thereby forming a chain link.
A chain link for a round or profile chain, comprising:
- a first chain link part;
- and
- a second chain link part, wherein the first and second chain link parts are connected by a linear friction welded bond, wherein the chain link parts are connected together along a welding plane lying in a separation plane of said chain link.
A round or profile chain, comprising:
- a plurality of chain links, interconnected to one another as a series of peripherally closed chain links, each chain link including:
- a first chain link part;
- and
- a second chain link part, the first and second chain link parts connected to one another by a linear friction welded bond, wherein the chain link parts are connected together along a welding plane lying in a separation plain of said chain link.
