Abstract: This application relates to a laser-plasma composite cladding head and a composite cladding method, and belongs to the field of surface processing of metallic materials. In the laser-plasma composite cladding head of this application, a ring laser beam is split into two half-ring laser beams through an upper roof lens to avoid a tungsten electrode. The two half-ring laser beams pass through a left 45° reflective lens to be coaxial with the tungsten electrode and then are integrated into a complete ring laser beam through a lower roof lens, thereby allowing a coaxial output of the ring laser beam and a plasma beam. This application integrates the advantages of laser cladding and plasma cladding and adopts coaxial compounding and synchronous powder-feeding.
