Abstract
A process for producing clad products that utilizes wrought or cast components eliminating the need for costly metal powders and a can to contain them. A sleeve circumscribes a core leaving a space therebetween. Powder is introduced into the space and is sealed therein. The resultant billet is extruded generating a clean metallurgical bond between the core and the sleeve. The space need not be evacuated prior to heating the billet. Resultant clad welding rod permits higher operating amperages.
