Abstract
The method for manufacturing a core comprises the following steps: providing a strip made of an electrically conductive material, shaping the strip into a tube, the two edges of the strip being substantially in contact, and welding together the two edges of the tube-shaped strip, via laser welding, in order to form the core (1). The method is preferably performed continuously using a continuous strip of substantial length, in an advantageous manner, the shaped and welded tube undergoes calibration, then a surface treatment intended to promote the adhesion of the insulating material (6) so as to insulate the core with respect to the external conductor (8) of the coaxial cable.
