Laser cladding is a new manufacturing technology booming in recent years. Many research have attempted to increase its level of automation and productivity by measuring the molten pool formed in the laser cladding with synchronous powder feeding. The research progress of the molten pool measurement and control technology in recent years is reviewed. Firstly ,various types of measuring equipment and installation methods are introduced. Then the influences of the processing parameters on the molten pool measurement signals and the relationships between the quality of cladding layers and molten pool measurement signals are presented. And then several closed loop control systems based on molten pool measurement technology are discussed. Finally ,based on the current molten pool measurement status,more useful information can still be further obtained to increase the degree of automation and improve productivity in laser cladding.
