ABSTRACT:
A method for manufacturing tubular conductors which consist of a niobium layer and a layer of normal electrically conducting metal in which a copper body of rectangular cross section is covered with niobium on one wide and two narrow sides by means of fusion electrolysis and the resulting body then rolled to form a ribbon which is then bent to form a tube with the niobium flanges at the two edges of the ribbon abuting and welded together by electron beam welding. Tubular conductors made according to the method of the present invention are particularly suited for use as superconducting cables.
