A method of welding at least two similarly configured thermoplastic sections together having relatively tight-fitting complementary joinder portions, said method comprising: preheating at least one of said sections in its joinder portion; sliding said tight-fitting portions together into telescopic conjoinment; oscillating said portions axially with respect to each other at a sufficiently rapid rate and for a sufficient period of time to generate enough heat to melt the areas of contact therebetween; and, bringing said sections into a final desirable position and allowing said heated areas to cool, thereby welding said sections together.
