A method of and apparatus for producing copper clad aluminum wire is provided in which a copper strip, while being formed into a cylindrical shape, is placed on the outer side of an aluminum core and the seam of the copper strip is then welded together to prepare a clad wire of the aluminum core and the copper strip, and thereafter the clad wire is subjected to a reducing process to produce a copper clad aluminum wire. The welding of the seam of the copper strip is effected in a closed atmosphere (shielding box) filled with an inert gas, and the diameter reducing operation is carried out through a die whose half-approach angle (i.e., a half approach angle) is between 35° and 55° and at a temperature below 200°C to insure a complete metallurgical bonding between the copper sheath and the aluminum core.
