ABSTRACT:
A tubular metal object is rotated about its longitudinal axis and a layer of tape and synthetic thermosetting resin is wrapped around the object at room temperature. The object is inductively heated substantially uniformly through its thickness a plurality of times progressively from one end to the other subsequent to the wrapping to a temperature sufficient to allow the resin to flow on the outer surface of the object. The object is further inductively heated to a temperature at which the resin will cure, and the object is then cooled to room temperature.
