Abstract: 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(14), comprising a resistance welding device (24) having a welding electrode (26) that can be deployed into and withdrawn from the working region (10), comprising a supply device (28) for supplying and transferring a respective hard material element (4) to the welding electrode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

Abstract: The invention relates to a method for joining hard material bodies to teeth of a saw blade, in particular of a band saw blade or circular saw blade, wherein each tooth has a tooth face and a tooth back, and the method includes the following steps: bringing each tooth of the saw blade into a working region; guiding each hard material body toward the tooth located in the working region; advancing a joining device into the working region; joining the hard material body to the tooth located in the working region; and withdrawing the joining device out of the working region. According to the invention, each hard material body is joined to the tooth back of each tooth.

Abstract: The invention relates to a method for welding hard material bodies to teeth of a saw blade, in particular of a band saw blade or circular saw blade, wherein each tooth has a joining surface, and each hard material body has a joining surface. The joining surface of the hard material body can be welded to the joining surface of the tooth. The method has the following steps: bringing each tooth of the saw blade into a working region; guiding each hard material body towards the tooth located in the working region; advancing a welding device into the working region; welding the hard material body to the tooth surface of the tooth located in the working region; and withdrawing the welding device out of the working region.
