Abstract
Workpieces for example pipes 10, 12 of polyethylene or other plastics material are joined by fusion by heating end-faces 40,42 by hot air from a blower 24 and heater 26 then forcing the faces together between a sleeve 30 and an outer annular wall 50. The pipes are held in clamps 16,18 relatively movable by a hydraulic cylinder 20. The end faces 40,42 are forced together for a period during which melt zones at either side of the interface are confined by the wall 50 and the sleeve 30 as the melt zones cool. The structure 22 can slide along the pipes so that the wall 50 can be positioned opposite the sleeve 30 once the end faces have been heated to fusion temperature. Alternatively, the end faces 40,42 are inclined to form a scarf joint. <IMAGE>
