Abstract: With the rapid development of laser manufacturing technology, laser technology had been widely applied in industry. The applications of laser manufacturing technology in the field of automobile, aerospace, iron and steel metallurgy demonstrate its advancement and universality in development ideas such as low energy consumption, short flow process and green environment protection. Two new-type lasers, i.e. high power semiconductor laser and fiber laser which represent future development direction of laser manufacturing systems are also introduced in hopes to change the current status of mainly relying on import of laser manufacturing equipment for use in large industry, and to form a new-generation laser manufacturing industry chain.

Key words: Laser cladding, Laser manufacturing, New-type lasers, Optics engineering
