ABSTRACT OF THE DISCLOSURE The present invention is the method of producing butt welds between pipes or ducts of fluoropolymers, which are extremely chemically inert and which have continuous service temperatures in the range of 300 to 500°F or more, by simultaneously applying infrared or radiant heat to the ends of the pipes or fittings to be welded but without touching the ends being radiated. The radiant heat is derived from a flat faced electric quartz infrared heater which has a surface temperature in excess of 1600°F and which maintained for fifteen to forty five seconds at a spacing of approximately one fourth to one half of an inch from the end face of the duct. The time varies with the size of the pipe being welded; and the heater to pipe spacing may vary widely, from 0.125 inch to as much as 2.0 inches.
