Abstract
A method of manufacturing an extruder barrel is disclosed which fabricates a barrel in two longitudinal sections and joins the sections together by electron beam welding. In a preferred form, the barrel sections are formed by machining conical recesses longitudinally in each section whereby a complementary bore is defined by the assembled barrel sections. The machined recesses may be formed with spiral, longitudinal or radial grooves. The recesses may be a uniform conical shape, stepped conical or a dual tapered shape.
