Forging a nail. Valašské muzeum v přírodě, Czech Republic. Forging is one of the oldest known metalworking processes. [1] Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could ...
Upset forging increases the diameter of the workpiece by compressing its length. Based on number of pieces produced this is the most widely used forging process. Upset forging is usually done in special high speed machines; the machines are usually set up to work in the horizontal plane to facilitate the quick exchange of workpieces from one ...
Heading is a metalworking process which incorporates the forging, extruding and upsetting process. [1] [dubious – discuss] It is often performed in the cold state, resulting in cold working.
A parameter would be set to apply the upsetting force until a certain distance has been upset. It is generally the upsetting distance that is more important than the upsetting time. At the end of upsetting there is commonly a 'hold time' during which the joint is held still to allow the joint to cool and the two pieces of metal to completely bond.
Step 4, upsetting stage: the welded elements are still forging by forge pressure (pressed down), Step 5: in standard RFW welding (standard parameters), a flash will be created. Outside flash can be cut off on the welder.

Friction welding (FWR) is a solid-state welding and bonding process that generates heat through mechanical friction between workpieces in relative motion to one another. The process is used with the addition of a lateral force called "upset" to plastically displace and fuse the materials. [1]
