ABSTRACT:
A friction welding method and apparatus for holding and joining thermo-plastic resin elements together by rotational torque friction. The method includes precise orientation of the joined surfaces together, applying pressure to the elements and precisely controlling a pre-determined rotation of the rotatable element against the fixed element within a fraction of a second achieving welding of the thermo-plastic part. Precise starting and stopping of the rotatable element achieves a rapid superior weld joint between the elements.
