The bucket is a structural product and is composed of bucket tooth holder plate, baseplate, side plate, side reinforcement plate, anchorage plate assembly, bucket tooth, tooth holder, and side blade. Therefore, the welding is the most critical fabrication process for the bucket and the welding quality directly influences the structural strength and service life of the bucket. The bucket can be classified by material to standard bucket, reinforced bucket, and rock bucket.
The elaborate choice of high strength wear-resistant steel plates with yield strength above 100MPa, the wear-resistant bucket teeth, and other high strength plates, the strict implementation of the world’s leading Komatsu KES welding standard and process, the use of all-dimensional welding positioner for critical welds, and the stringent fabrication process of 100% non-destructive inspection for critical welds guarantee the high reliability of the bucket.
