Abstract: According to the characteristics of the coaxial wire feeding laser cladding technology, the annular beam scheme, three beams scheme, and four beams scheme were analyzed respectively, the advantages and disadvantages of different design schemes were compared, and the finite element analysis of the optical path convergence effect was carried out. The results show that when using a parabolic mirror and planar mirror, the convergence effect of the annular beam scheme and three beams scheme is stronger than that of the four beams scheme. The parabolic mirror is stronger than the plane mirror scheme for the focus position energy. Due to the laser beam's poor convergence effect and complex structure, the four beams scheme does not meet the practical application requirements. The convergence effect and focus of the energy of the annular beam scheme are not much different from the three beams scheme. However, when designing the wire feeding path, the three beams scheme can avoid the interference of the optical wire and make the wire feeding path layout more reasonable and stabilize the wire feeding process. In conclusion, the three beams paraboloid scheme is the best scheme for the design of a laser cladding head optical path with the coaxial wire feeding.
