Upset forging increases the diameter of the workpiece by compressing its length. [18] Based on number of pieces produced, this is the most widely used forging process. [18] A few examples of common parts produced using the upset forging process are engine valves, couplings, bolts, screws, and other fasteners.
Drawn out: length increases, cross-section decreases 2. Upset: Length decreases, cross-section increases 3. Squeezed in closed compression dies: produces multidirectional flow. Common forging processes include: roll forging, swaging, cogging, open-die forging, impression-die forging, press forging, automatic hot forging and upsetting.
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.
