The connecting bolts at the root of wind turbine blades are subjected to alternating loads and outdoor corrosion. Traditional high-strength bolts have a service life of only 5-8 years, and replacement requires high lifting costs. The Daokedao automated laser cladding equipment uses Ni60A nickel based alloy powder to fuse a 2mm strengthening layer on the bolt threads and head transition areas. The hardness of the cladding layer is HRC50-55, the fatigue strength is increased by 30% compared to the original bolt, and the salt spray corrosion resistance reaches 2000 hours. A case study of a wind farm shows that the service life of bolts after melting has been extended to 15 years, and the failure rate of bolt fracture has decreased from 3% to 0. A single wind turbine can save maintenance costs of over 150000 yuan per year, and the equipment's bolt specific rotating melting technology ensures thread accuracy.
