ABSTRACT:
Plastic tube sections are connected together by providing a pair of tubes each of which is inserted into the holder of a welding device in a bent condition so that each tube has a primary tube section and a secondary tube section with the primary tube sections being aligned with each other and the secondary tube sections aligned with each other. The tubes are heated by a wafer to create four separate tube sections which are then joined together in a dual weld wherein one of the welds joins the primary tube sections together and the other of the welds joins the secondary tube sections together. The welded primary tube sections are then separated from the secondary tube sections. Communication between each pair of tube sections is achieved by pressing the tube section open at the weld.
