When repairing severely worn bucket teeth using D266 welding electrodes for surfacing welding, excavator bucket teeth manufacturers adopt the following method: they first weld a patch plate, cut from a tractor crawler track plate (made of high manganese steel), to the tooth tip, and then perform surfacing welding. The size of the patch plate is determined based on the degree of wear. During welding with D266 welding electrodes, a symmetrical and alternating welding sequence is adopted to prevent cracking.
