Plastic tubes are welded by placing a pair of tubes in a pair of aligned holders with each tube folded toward itself. A wafer is movably mounted in the gap between the tubes and is heated to cause the ends of the tubes to melt without actually cutting through the tubes. The melted ends of opposed tubes can be pressed into contact with each other to form a welded connection. In a variation a pair of cutting blades cut the folded ends of the tubes and the cut ends are then melted by a wafer and subsequently pressed into contact with each other.
