The invention discloses a laser cladding process. The laser cladding process comprises the following steps: putting YCF101 powder in a drying box, drying the YCF101 powder for 5h at a constant temperature of 80 DEG C, then pouring the YCF101 powder into a laser cladding powder feeder, and performing powder feeding coaxially for cladding; grinding a substrate, and cleaning the substrate with alcohol to remove impurities so as to obtain a smooth to-be-cladded substrate; and performing laser cladding layer by layer on the smooth to-be-cladded substrate by employing a IPG optical fiber laser according to a certain laser processing parameter and a certain laser scanning policy. According to the laser cladding process disclosed by the invention, defect accumulation as powder is stuck to a lap joint by way of single form interlaminar lap joint is weakened effectively. The extension direction of the defects is consistent to an interlayered scanning track. By crossed longitudinal interlaminar lap of multiple groups, the defects are uniformly distributed on the cladding plane, and the defect degree is reduced effectively; the extension direction of a bath is also consistent to the scanning direction, so that the high temperature of the bath in the next layer also alleviates pores at the lap joint effectively.
