The invention provides a production method for a copper-titanium composite tube. The method comprises the following steps: (1) sleeving a processed titanium tube in a copper tube and welding one end of the titanium tube and one end of the copper tube so as to form a composite tube blank; and (2) rolling the composite tube blank and carrying out composite drawing and annealing.
