Forge welding
Joining two pieces of metal by heating them to a high temperature and then hammering them together / From Wikipedia, the free encyclopedia
Forge welding (FOW), also called fire welding, is a solid-state welding process[1] that joins two pieces of metal by heating them to a high temperature and then hammering them together.[2] It may also consist of heating and forcing the metals together with presses or other means, creating enough pressure to cause plastic deformation at the weld surfaces.[3] The process, although challenging, has been a method of joining metals used since ancient times and is a staple of traditional blacksmithing.[4] Forge welding is versatile, being able to join a host of similar and dissimilar metals. With the invention of electrical welding and gas welding methods during the Industrial Revolution, manual forge-welding has been largely replaced, although automated forge-welding is a common manufacturing process.
