The invention relates to a preparation method of a laser-cladding reinforced shunt taper, which mainly comprises the steps that after a common medium-low carbon alloy structural steel bar is machined according to a shunt taper drawing, a part contacted with molten aluminum is reduced by 0.5mm according to the size, and then continuously machined; metal ceramic alloy powder is prepared, wherein the metal ceramic alloy powder comprises the following chemical components by mass percent: 0.1-0.35% of C, 0.6-1.2% of Al, 0.7-0.9% of Si, 25-29% of Cr, 55-62% of Co, 2.1-2.8% of Yb, 4.3-4.9% of W, and the balance of Fe; the power is conveyed on the shunt taper by adopting a pneumatic or gravitational mode; high-energy light beams of a high-power semiconductor laser device are used for scanning, so that the alloy powder conveyed in place and metal on the surface of a substrate of the shunt taper have a quick metallurgical reaction; stress relief annealing is conducted on the laser-cladding shunt taper for 2-4h at 300-500 DEG C; slow furnace cooling is conducted; and finish machining of an alloy reinforcing layer is accomplished by a numerical control machine tool. The method is simple in preparation technology and pollution-free, and the prepared reinforced shunt taper is long in service life and low in cost.
