ABSTRACT:
A rod made of a hard material is inserted into a pipe made of a relatively soft material, and a two-element arrangement having an intermediate size is obtained by hot-rolling and drawing. In these steps, the cross section is reduced by at least 50%. Subsequently, another pipe of the soft material is fitted onto the two-element arrangement, and the so-obtained three-element arrangement is adjusted to its final size by means of hot or cold rolling followed by cold drawing.
