Spin Welding as the name implies, is a friction welding technique to join thermoplastic parts. It is essential the parts to be joined or atleast their joint areas must be circular for this method of joining to be used. A shallow Machining groove (tongue & groove) is desirable to index the two parts and to provide a uniform bearing surface.

With one part held stationary, either vertically or Horizontally, in a special fixture, the other is rotated at *******0 rpm with enough pressure applied to keep the parts in contact with each other. The heat generated in friction is used to bring the surfaces to a sealing temperature. When sufficient melt is obtained, the spinning stops and the pressure is increased to distribute the melt and also to squeeze out excessive melt, completing the general process.
