Diffusion Welding (DFW)
SSW process uses heat and pressure, usually in a controlled atmosphere, with sufficient time for diffusion and coalescence to occur
Temperatures ≤0.5 Tm
Plastic deformation at surfaces is minimal
Primary coalescence mechanism is solid state diffusion
Limitation: time required for diffusion can range from seconds to hours
