ABSTRACT:
A spinwelding procedure is provided for joining thermoplastic tubular members together at their respective axial ends. Axial end portions of very thin tubes are circumferentially supported both internally and externally, and one of the tubes is then rotated with respect to the other until adequate friction develops to melt the thermoplastic materials, after which they cool to heat bond together.
