STRUCTURAL MATERIAL REPAIRING ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a compact build-up welding device not requiring two kinds of electrodes, a heating electrode and a build-up welding electrode. SOLUTION: An electrode 2 is formed in a disk shape; and its peripheral part discharges electricity to a structural material to conduct build-up weld repairing based on the output from an output control board. The electrode 2 is rotated in the peripheral direction by a motor 3 operated by a driving machine controller 5, and conducts the build-up welding by uniformly discharging its peripheral part. A feeding mechanism of electrode wire is not required by preliminarily recognizing a required build-up amount and preparing an electrode having an outer diameter and a thickness corresponding to the build-up volume and thus simplification of the device is realized.
