IMPROVEMENTS IN OR RELATING TO FINNED TUBING HAVING RESISTANCE-WELDED FINS
Patent

OSTI ID:4151647
A method is proposed for the manufacture of finned tubing by attaching fins to tubing; such tubing is suitable for use in heat exchangers for gas-cooled reactor power plants. The method consists of winding U or channel-sectioned metal strip helically around a tube and securing the strip base to the tube surface by electric resistance seam welding. The welding is done with roller electrode devices, and various arrangements for welding are shown, including one in which protuberances are spaced helically on the tube and the strips wound in register with these protuberances.
