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.
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer ) or a die . Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working ), warm forging, or hot forging (a type of hot ...

Forming processes tend to be categorised by differences in effective stresses. These categories and descriptions are highly simplified, since the stresses operating at a local level in any given process are very complex and may involve many varieties of stresses operating simultaneously, or it may involve stresses which change over the course of the operation.
Gear manufacturing refers to the making of gears. Gears can be manufactured by a variety of processes, including casting , forging , extrusion , powder metallurgy , and blanking . As a general rule, however, machining is applied to achieve the final dimensions, shape and surface finish in the gear.
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 ...
The process combines the advantages of casting and forging. The process is named after the fluid property thixotropy, which is the phenomenon that allows this process to work. Thixotropic fluids flow when sheared, but thicken when standing. [3] The potential for this type of process was first recognized in the early 1970s. [3]
