SELECTION OF THE PROCEDURE, FILLER MATERIAL AND HARDFACING TECHNOLOGY
The role of bucket teeth (Figure 1a) is to separate and crush stone material and to protect the bucket against wear. The number and shape of teeth depends on the application (trench digging, gravel digging, material loading, etc.) and the size of the bucket, varying from three (trencher buckets) to fifteen teeth (buckets of bigger loaders). They can be installed in two ways: bolted directly to a bucket or their holder can be welded to a bucket and the teeth are bolted onto the holder. Teeth are made of cast steel or cast iron; their mass ranges from 3 kg to 15 kg per piece.
