摘要：
A laser cladding system (10) comprises a cladding head (12) and a gas system (50). The cladding head (12) extends along a primary axis (A P ), and comprises a mirror (30) and a powder nozzle (34) both situated at a distal end (22) of the head (40). The powder nozzle (34) directs weld material at a target point (P T ), and the mirror (30) directs a beam (28) of collimated light at the target point (P T ). The gas system (50) comprises a high-speed gas nozzle (304) and a gas knife (310). The high-speed gas nozzle (304) produces a gas sheath (302) coaxial with the beam (28) in a region between the mirror (30) and target point (P T ), shielding the mirror (30) from debris and backspatter. The gas knife (310) redirects the gas sheath (302) away from the target point (P T ) and redirects debris and molten backspatter away from an interior of the laser cladding head (12).
