The paper describes the posibilities to apply the friction stir welding to join the solid copper wires from the electrical generators within the power plants. The figures in this paper show the copper wires from the electrical generators, and their impellers. The welded joints obtained by WIG process and by friction stir welding were been the same results obtained for the base material. A comparison between the results obtained using the new technology, and the results obtained by another old technologies, such as fusion welding and bonding, was been made.
