The invention discloses a preparation method of a magnesium alloy welding wire. The preparation method of the magnesium alloy welding wire comprises the steps of ingoting extruding, wire billet clearing, preheating, continuous extruding, pulling, skiving and surface treatment, specifically, in the continuous extruding, materials are continuously fed into an extruding machine, and the continuous extruding temperature is maintained at 380-450 DEG C by controlling the extruding speed and adjusting a temperature-control system. According to the preparation method of the magnesium alloy welding wire, the technology is simple, operation is easy, processing is efficient, the economic cost is low, continuous extruding is adopted, the processing performance of a magnesium alloy is greatly improved,the difficult problem of joint connection of the magnesium alloy welding wire is effectively solved, a high-quality magnesium alloy joint-free welding wire can be produced, the requirements of melting welding such as automat
