It is unwelded in the periphery, because PMMA with lower wear resistance tends to be worn and spun out during the friction welding
process; as a result, the opportunities for wetting, approaching, and molecular chain interdiffusion with PVC and PMMA are fewer.

For friction welding
, the beginning of the steady-state phase is characterized by a linear variation of the displacement with time; it can be assumed that the resulting welds are uniform and reproducible once the steady state has been attained.

But whereas friction welding
has had extensive use in the aerospace industry for making things like blisk assemblies for aircraft engines, it is now drawing greater attention in automotive.
 joined cylindrical pure Ti to 304 stainless steel by friction welding
with nickel as the interlayer, and NiTi, [Ni.sub.3]Ti, Ni[Ti.sub.2], and [Ni.sub.2]Ti intermetallic compounds were demonstrated at the joints instead of brittle TiFe intermetallic compounds.

is a solid state welding process where in coalescence is produces by the heat obtained from mechanically induced sliding motion between rubbing surfaces.
Vibration welding is a proven friction welding
technique capable of producing strong, pressure-tight joints in the thermoplastic parts.
