A dual-alloy cladding layer wear plate and a preparation method relate to the field of wear plate of a concrete pumper. Bores of a wear plate matrix and inner rings of glasses are cladded with ferrous alloy by laser; and outer rings of the glasses are cladded with nickel tungsten alloy by laser. The ferrous alloy comprises chemical components of 0.40-0.70 wt% of C, 2.0-3.0 wt% of B, 20-24 wt% of Cr, 4-7 wt% of Ni, 1.8-3.0 wt% of Si and the balance of Fe. The nickel tungsten alloy comprises chemical components of 2.2-2.7 wt% of C, 10-13 wt% of Cr, 1.8-2.8 wt% of Si, 50-60 wt% of W, 1.5-2.4 wt%of B and the balance of Ni. In order to prolong a service life of the wear plate and according to failure characteristics of different working positions, different alloy materials are cladded by laser to reach the goal of saving precious metal materials and reducing processing cost.
