To study effect of the matching of z-axis single increment (z) with single cladding layer height on laser cladding forming, experiments of laser cladding forming were carried out at different z. The relationship curves of different z, single cladding layer height and defocusing were obtained after theoretical analysis and experimental verification. The results show that the optimal range of z is based on the second cladding layer height. In this range, the process of cladding would reach a steady forming state by feedback regulation. A recommended value of z(0.5d2 z 0.6d2) is provided.
