Abstract
In a method for producing metal composite block material, the joining surfaces of composite block elements are machined by machine-cutting to a metallically bright state. Subsequently, the composite block elements are joined by electron beam welding to a composite block material. The composite block material is formed by steel extrusion to a composite pipe.
