Laser cladding technology has a wide range of engineering requirements for the repair of engineering components with high manufacturing technology requirements, long production cycles, high processing costs, and expensive engineering components. At the same time, it can optimize resource allocation, save precious and rare metal materials, reduce energy consumption, and save money. . The laser cladding repair technology is pollution-free and pollution-free, and has a strong role in protecting the environment, which belongs to the green remanufacturing project. From a long-term perspective, laser cladding technology will play an important role in precision repair with its unique advantages.
