Method for repairing abraded end face of arrester

The invention provides a method for repairing an abraded end face of an arrester. The method aims at achieving the effects of low cost, high efficiency, high abrasion resistance, and easiness in processing. The method adopts the technical scheme that a high-temperature alloy HGH625 welding wire and argon arc welding hard-face overlaying are adopted, and 1.8-2.0mm-thick overlaying is carried out on the abraded end face; an overlaid layer is polished manually till the size of the overlaid layer meets the using requirements; then the overlaid end face is coated with 0.04-0.05mm thick CoCrW alloy by adopting an electric spark coating method, wherein during coating, the coating voltage is 40-50V, the coating frequency is 500Hz, and the coating power is 800-1000W. With the adoption of the method, the problems in the prior art that after an abrasion-resistant layer is welded to the abraded end face by adopting coating or welding independently, the binding force is poor, the end face is not abrasion-resistant, an abrasion failure happens easily and quickly, coating shedding can be caused easily in a sliding abrasion process, and the size processing is difficult and the efficiency is low after hard alloy overlaying is carried out are solved.
