Laser cladding is a new surface technology that has been developed rapidly in recent years. The performance of laser cladding layer is influenced by various factors, among which temperature of molten pool is a key factor in particular. The temperature measurement and control of laser cladding molten pool play an important role in controlling the quality of laser cladding. We introduce the commonly used temperature measurement methods, and review the current research state in various control systems for molten pool temperature of laser cladding. Based on the review, the future development of temperature measurement and control is prospected.
