Solid-state welding processes are a group of technologies in which joining is accomplished without melting the individual substrates. In these processes, bonding is accomplished by a combination of heating and forging. Heating is used to both lower the flow stresses enabling forging, as well as promote diffusion between the individual substrates. Common variations of these...

Inertia welding is a well-established, friction-based, solid-state joining process. Many different applications use this welding process, ranging from aircraft engine parts to air bag inflators to hand tools. Process parameters associated with inertia welding (spindle speed, welding force, inertia, and displacement) have been widely studied since the process gained traction in the late 1960s. One...
