Experimental Studies of Clean-Ing Welding Wire by High-Voltage Electrochemical Method

Abstract

This article presents the results of studies of the high-voltage electrochemical cathodic process of cleaning the welding wire from scale, rust and other contaminants, since the quality of the weld significantly depends on its condition. The es-sence of high-voltage electrochemical cleaning is described, according to which electrolyte is supplied to the treated surface of the workpiece by a narrow stream from the holes of the sprayer nozzle. The description of the experiments is given. The authors note the influence on the stable course of the cathodic process and the quality of cleaning of the electro-hydraulic and technological parameters of the process. They determined the absence of the welding wire hydrogenation, which is explained by the specificity of phase transformations in the near-cathode zone. Rational regimes for cleaning the welding wire are given.
