摘要：Separate segments, oversized to allow for shrinkage during welding, areassembled in the shape of a ring. The segments may be plates carrying guide vanes. Theassembled ring is placed in a vacuum chamber and the joints between segments weldedby an electron beam. The welding may be carried out in two steps, namely, first trackwelding the segments together followed by finish welding the entire length of each joint.The segments may be held during welding in a fixture comprising a circular array ofradially-slidable jaw elements which carry the separate segments. A clamping ring urgesthe jaw elements, and hence the segments, radially inwardly, and a cover plate engagesthe separate segments and urges them radially inwardly so as to clamp the segmentstogether in a ring shape.
