The invention relates to a device (2) for welding hard material elements (4) onto teeth (6) of a saw blade (8), comprising a saw blade feed device (12) for moving the saw blade (8) in a feed direction (14), such that a tooth (6a) of the saw blade (8) can be brought into a target position (16) in a working region (10) of the device (2), comprising a first centering device (30) for centering the saw blade (8) transversely to the feed direction (14), comprising a second centering device (32) for centering a respective hard material element (4) transversely to the feed direction (14), comprising a resistance welding device (24) having a welding electrode (26) that can be deployed into and withdrawn from the working region (10), comprising a supply device (28) for supplying and transferring a respective hard material element (4) to the welding electrode (26), and it being possible for the welding electrode (26) to be deployed in such a way that the hard material element (4) can be brought toward the tooth (6a) to abut the tooth (6a). According to the invention, the hard material element (4) can be centered relative to the centered and fixed saw blade (8) by means of the second centering device (32), and the first and second centering device (30) are provided in a common assembly (38), such that the centering of the saw blade (8) by the first centering device (32) predetermines a centering position for the subsequent centering of the hard material element (4) by the second centering device (32).

The invention relates to an arrangement for setting saw teeth on a saw band (4), the arrangement having a base (1) through which the saw band can slide. The base has a receiving device (6) for receiving a saw tooth setting device (8). The saw tooth setting device (8) can set saw teeth in one direction. The receiving device (6) can receive the saw tooth setting device (8) on both sides of the saw band, so that the saw tooth setting device (8) received on one side can set the saw teeth in one direction and so that the saw tooth setting device (8) received on the opposite side can set saw teeth in the opposite direction. This means that although only a simple saw tooth setting device (8) arranged to be able to set saw teeth in one direction is used, the device for setting saw teeth can set them in both directions.
