The linear table takes the rotary table with the steel center to the welding station where the steel center is clamped pneumatically. The segments are conveyed to the welding station by the individual segment feeders and clamped pneumatically. The segment is welded on the steel center by means a path-controlled laser beam. The clamping fixtures of the steel center and the segments are released, the steel center moves on one welding position and a new segment is fed. The steel center and the segment are clamped and welded together. These sequences are repeated until all segments are welded on the steel center. The rotary table with the welded saw blade moves to the blade changing position where the blade is taken out either manually or by means of the blade exchanger. LSM 300 page 3 of 5 V05052017; sz
