Solid State Welding (SSW)
Coalescence of part surfaces is achieved by:
Pressure alone, or
Heat and pressure
If both heat and pressure are used, heat is not enough to melt work surfaces
For some SSW processes, time is also a factor
No filler metal is added
Each SSW process has its own way of creating a bond at the faying surfaces
