如图，环形光内送粉激光熔覆系统主要由激光器、自研环形激光熔覆加工头、机械臂、送粉器、系统控制柜、杜瓦罐以及冷水机组成。其中，系统控制柜集成了激光器的触发、功率参数调整与保护气流量、载粉气流量调整等功能。除此之外，送粉量由送粉器单独控制；杜瓦

As shown in the figure, the laser coating system is mainly composed of laser, self-researched ring laser coating processing head, mechanical arm, powder feeder, system control cabinet, Dewar tank and chiller. Among them, the system control cabinet integrates the functions of laser triggering, power parameter adjustment and protective gas flow, and powder carrier gas flow adjustment. In addition, the powder feeding volume is controlled separately by the powder feeder; Dewar
