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 ...
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

Pattern welding is a practice in sword and knife making by forming a blade of several metal pieces of differing composition that are forge-welded together and twisted and manipulated to form a pattern. [1] Often called Damascus steel, blades forged in this manner often display bands of slightly different patterning along their entire length.
Archeologists believe that spheroidal hammerscale is produced primarily during the process known as fire welding. Also known as forge welding, this technique is used to connect two pieces of metal by heating them to a high temperature and forcing them together with a hammer or other tool. For this method to be successful, the surface of each ...
