ABSTRACT:
A bucket with a bottom wrapper sheet and adjacent side plates has strips of material welded thereto at critical wear areas. The strips have a plurality of inserts of a hard wear-resistant material bonded into openings in said strips, which strips and inserts are heat treated prior to welding to the bucket. When excessive wear of the strips and inserts has taken place, the strips are removed and new strips with new inserts are welded to the wear areas of the bucket. A method of making and applying wear strips to a bucket is disclosed which includes the steps of forming and shaping the strips, drilling cavities into the shaped strips, bonding preformed inserts in said openings, heat treating the strips with the inserts bonded therein, and attaching the strips to said bucket.
