Provided is a repairing method for a blade of a carry-scraper bucket. The repairing method comprises following steps of: 1) preparation before welding; 2) edge preparation; 3) welding technology; 4) post-welding operation: machining and grinding of a welding position and confirmation that a welding seam does not have defects of quality after flaw inspection; when the requirement for JB4730-94 standard I-level is satisfied by welding quality and average hardness value of the surface of the welding position reaches at least HB449, repairing operation is finished. The invention relates to the repairing method for the blade of the carry-scraper bucket with the purpose of overcoming problems in the prior art. Provided is the repairing method for the blade of a carry-scraper capable of not only repairing the blade but also increasing working intensity of the bucket, thereby ensuring using effect and service lifetime after repairing operation.
