A method of making a frusto-conical centrifuge screen basket of side-connected segments formed of wedge-shaped screen wires connected and backed by tie bands welded thereto, in which the segments are each fabricated in the flat by clamping laterally spaced screen wires to a flat work surface and fusion welding laterally spaced tie band sections to the screen wires, and the tie band sections are so precurved and positioned during welding as to form in the finished basket a plurality of laterally spaced parallel continuous circumferential tie bands each centered on and perpendicular to the basket's axis and together reinforcing the basket against centrifugal forces imposed in service.
