| Abstract: | The processing and properties of copper-clad steel wire produced by pipe-weld cladding technique were studied. The starting materials, steel wire with a carbon content of 0.1 per cent for core and copper strip for clad layer, were degreased and brush cleaned. The copper strip was formed to a pipe shape encircling the steel wire, and the seam was welded longitudinally to form wire billet. Then the billet was drawn through a number of dies until to its final size. Metallurgical analysis, mechanical properties testing and electrical resistivity measurement were carried out, and the results showed that the copper-clad steel wire produced by this method meets the requirement of ASTM standard for CATV drop wire. |
