We present a method of determining the geometric characteristics of gas-powder flow during laser cladding with coaxial injection. We evaluate the effect of the operating parameters (feed rate and channel width of powder injection) on the geometry of particle flow. Optical diagnostics of the laser cladding is carried out by an infrared camera.
