DISC ASSEMBLY WITH WELDED DISCS ABSTRACT OF THE DISCLOSURE A disc separator includes discs welded to a hub. Each disc has an extruded collar disposed around a central aperture through which the hub extends. The collar provides bending rigidity to the disc and is interposed between the disc and hub to insulate the disc from thermal stresses caused by welding. The hub has an open seam and an initial diameter less than the diameter of the central aperture of the discs. The discs are assembled on the hub by sliding each of them to a predetermined position on the hub, expand- ing the hub, welding the collar to the hub, and relaxing the hub. The steps are repeated until a plurality of discs are securely welded to the hub to form a disc assembly.
