Solid State Welding Processes - A solid state welding process produces coalescence at temperatures essentially below the melting point of the base materials being joined, without the addition of a filler metal. Pressure is always applied.
The following solid state welding processes will be discussed in this chapter:
1. Cold welding
2. Diffusion (bonding) welding
3. Ultrasonic welding
4. Explosive welding
5. Friction welding and Inertia welding
6. Forge welding.
