Abstract
A method and apparatus for manufacturing a coiled tubing/electrical cable assembly wherein a strip of metal and electrical cable are simultaneously withdrawn from storage reels and are moved through a manufacturing station where the metal strip is formed about the cable and welded to define coiled tubing. The electrical cable is guided into the tubing by a cable placement tube that also serves to conduct coolant such as air, water, etc. along the electrical cable to prevent its temperature degradation during the manufacturing process. The cable placement tube is of sufficient length to extend past the welding apparatus and through a heat treating furnace assembly and to provide an outlet for discharge of the coolant medium into the coiled tubing cable at a location downstream of the heat treating furnace.
