The invention relates to the technical field of anode steel claws, in particular to an anode steel claw repairing method which comprises the following steps: S1, claw head cutting; s2, hoisting the steel claw before repairing; s3, roughly grinding the steel balls; s4, steel grit fine grinding; s5, manufacturing a sand mold; s6, melting the claw head; s7, casting the molten steel; s8, a welding surface is trimmed; s9, plugging with refractory mortar; s10, welding is conducted; s11, hoisting the repaired steel claw; s12, repairing and polishing; and S13, checking and accepting. The corrosion surface on the outer side of the steel claw is removed through steel ball pre-steel sand polishing, the cleanliness of the steel claw is improved, follow-up repairing operation is facilitated, a damaged claw head is cut off, welding is conducted in an ultrasonic welding mode, the firmness of the repaired steel claw is improved, the durability of the steel claw is facilitated, the cut claw head can be reused, and the service
