A spinning roller surface laser reinforced processing forming method is provided. A spinning roller is normalized after forging, the normalizing temperature is controlled to 860-880 DEG C., and the heat preservation time is 40-60 minutes; the spinning roller forging blank is roughly processed to reserve a tolerance allowance of 0.5 mm on the designated working face; the spinning roller and workpiece contact surface reinforcing layer is made of Ni625+WC2, in which WC is more than 22%; a reinforcing layer having the thickness of 0.8 mm is clad with laser on the working face of the spinning roller, and the preheating temperature is controlled to 250-400 DEG C. before welding; the spinning roller laser clad reinforcing layer is rolled; and the rolled spinning roller is put into a thermal treatment furnace for thermal treatment, and quenching and tempering treatment, re-crystallization and residual stress elimination are performed.
