A method and apparatus for fabricating uniform splices for stranded cables. A joint for a stranded cable can be formed by inserting the ends of two cables into an electrically conductive splice band which, in turn, is inserted into a coil or inductor. The splice is fabricated by a process known as magnetic pulse forming, or magnetic pulse welding wherein a very large electrical current of short duration is directed through the coil or inductor from a charged capacitor bank. The resulting magnetic field in the coil or inductor induces a magnetic field on the splice band, compressing the splice band uniformly around the circumference of the two cable ends being spliced. In the case of magnetic pulse welding, the splice not only uniformly compresses the stranded cables, but a weld is also created between the inner diameter of the sleeve and the adjacent stranded cables.
