Cold welding - Wikipedia

Cold welding or contact welding is a solid-state welding process in which joining takes place without fusion or heating at the interface of the two parts to be welded. Unlike in the fusion-welding processes, no liquid or molten phase is present in the joint.. Cold welding was first recognized as a general materials phenomenon in the 1940s. It was then discovered that two …
