COAXIAL WIRE FEED MULTI-LASER METAL DEPOSITION DEVICE

A coaxial laser metal deposition head includes a wire guide and a plurality of laser optical units. The wire guide defines a wire guide axis. The laser optical units are distributed around the wire guide axis. Each of the laser optical units is connected to a separate laser and each defines a beam axis. The optical units are fixed relative to the wire guide and in a first condition are positionedto allow each of the beam axes to intersect the wire guide axis at a common point. 一种同轴激光金属沉积头部，其包括金属丝引导件和多个激光光学单元。所述金属丝引导件限定金属丝引导件轴线。所述激光光学单元围绕所述金属丝引导件轴线分布。每个激光光学单元连接到单独的激光器，并且每个激光光学单元限定光束轴线。所述光学单元相对于所述金属丝引导件固定，并且在第一状态下定位成允许每个光束轴线在公共点处与所述金属丝引导件轴线相交。
