The production of copper clad aluminum wire by the cladding welding method is to send the copper tape and the aluminum core wire that have been cleaned of surface oxides into the covered welding device, and at the same time, the copper tape is gradually formed into a round tubular shape around the aluminum core wire, and the aluminum core wire is Wrap Then use argon-arc welding, will continue to move forward and copper tube longitudinal seam welding, forming copper clad aluminum wire billet; then the wire billet after multi-pass drawing, so that copper and aluminum metallurgical combination, to obtain a certain diameter and required The electrical performance of the copper clad aluminum wire; Finally, through the heat treatment method to give the finished product the required mechanical properties.
