Abstract
A process for forming metal components of controlled porosity by welding, in which a predetermined amount of metal elements ( ) of oblong shape is introduced into a mold ( ) in which it is distributed isotropically. The metal elements are then subjected to increasing pressure (P) until the component has its final shape. The walls of the mold are then held in position and an electric current (I) flows through the metal elements and welds them together by local melting at the points of contact due to the Joule effect.
