Abstract
A method of processing heated metal logs in a metal extrusion process. The remainder of each log is attached to the succeeding log. Specifically, the abutted ends of the two log segments are aligned with a saw. The saw is actuated to simultaneously remove material from both of the abutted ends. The cut ends are friction welded together through relative rotation of the log segments. The process creates a heated log column that is effectively endless, eliminating log remainders.
