The head part of the key components of the wind turbine is at a high altitude. Once damaged, it needs to be hoisted, disassembled, and then repaired and replaced on the ground, which resulting in high maintenance costs. There are safety hazards in high-altitude hoisting, and affects the efficiency of power generation. It becomes an urgent problem for wind farm owners to solve the problems of on-site repair without dismantling and hoisting by seeking suitable technology. Online repair is totally feasible to repair of key transmission components such as pitch ring gear, main shaft, yaw brake disc, gearbox gear, yaw ring gear, etc. according to the research data of the wind power operation and maintenance market combined with the laser cladding technology in other industries on-site repair cases.
